with scott pelley. >> pelley: u.s. intelligence is working against a deadline of january 20th, the day president obama leaves office, to complete the investigation he ordered of attempts by foreign hackers to influence the election. one focus is the russian break-in at the democratic national committee. we know a lot more about that tonight thanks to jeff pegues. >> reporter: investigators believe the attack began in july of 2015, more than a year before the presidential election. thousands of e-mails were sent to hundreds of organizations. ultimately the hackers known as cozy bear and tied to russian intelligence burrowed into the computers of the democratic national committee, and they stole documents and e-mails that would later come back to haunt democratic presidential candidate hillary clinton. adam hodge is with the d.n.c. >> this is unprecedented. a foreign government attacked the entire democratic party with

one goal, and that was to help donald trump. >> reporter: the u.s. intelligence community is split on whether the hacks were intended to help mr. trump, but since at least 2010, u.s. intelligence analysts have been warning of russian cyber intrusion and information warfare. a 2013 threat assessment concluded russia is among three countries focusing on using internet content that might contribute to political instability and regime change. with the d.n.c. hack, an f.b.i. agent first noticed these suspicious activities earlier this year. he called the d.n.c. and was transferred to a help desk. his calls went ignored. >> it took several months before the d.n.c. realized that it had been contacted by the f.b.i. >> to verify the authenticity of the f.b.i. agent that said who he said he said he was. >> a couple of months? >> it's hard to believe, but that's the reality. >> reporter: president-elect

trump has brushed off allegations that the russians were trying to boost his candidacy. he recently tweeted, "unless you catch hackers in the act, it's hard to determine who is doing it." and he wondered why this wasn't brought up before the election. >> pelley: jeff pegues for us tonight. donald trump's election could cost him a prized possession. he recently converted a washington landmark enter a luxury hotel. but the old post office built in 1899 is still owned by the government, and that's a problem. here's julianna goldman. >> one, two, three. [applause] >> reporter: to build his newist hotel here in the nation's capital, president-elect donald trump leased the building from the federal government. the contract included a standard clause that says, "no u.s. elected official can be part of the lease or privy to any benefit from the deal." that means the day mr. trump takes office, he'll be in breech of contract unless he cuts all financial ties to the hotel. >> they need to resolve it as

soon as possible. >> reporter: congressman elijah cummings says a top official from the general services administration, which oversees the property, recently told democrats they tried to reach the trump team but haven't heard back. >> we want the american people to have trust in the decisions that the president makes, and by eliminating these conflicts, you then open a door for that. >> reporter: while he's in the legally obligated, mr. trump has said he'll separate himself from his businesses but this week postponed a conference to lay out how he'll do it. instead he tweeted prior to his inauguration he'll turn over his business to his two adult son, also problematic since they're actively involved in the transition, and the d.c. hotel is a prime example according to steven sciewner, an expert on government contracts at the george washington university law school. >> just try to imagine a civil

servant negotiating with the president's adult children knowing that their supervisor was appointed by the president. >> reporter: the g.s.a. said they will wait to see what from trump does with his businesses before taking any action. the trump organization did not respond to our request for comment. >> pelley: julianna goldman, thanks. mr. trump met today in new york with billionaires who, for the most part, did not support him. and he had a message for the chief executives of silicon valley. major garrett is covering the transition. major? >> reporter: scott, the president-elect told technology executives he wanted to work with them, but one company was con conspicuously absent, america's most influential twitter user did not invite that social media company to the meeting. c.e.o.s from apple, amazon, microsoft and google as well as others were summoned to trump tower, but twitter, according to the trump transition, was not invited because it lacked the economic clout of the other invited companies. now, there has been bad blood between twitter and the trump

team. during the campaign in its latter stage, trump officials wanted the social media company to create a custom icon to accompany mr. trump's nickname and hashtag for hillary clinton, "crooked hillary." twitter initially agreed but later backed out, rejecting the emoji's design. scott, there is no proof that disagreement had anything to do with twitter's absence today. >> pelley: major, thank you very much. the president also told those executives he would do everything he can to support innovation. the president-elect's first overseas crisis is likely to be syria, and today the agony of aleppo deepened as a negotiated ceasefire failed the minute it began. tonight time-lapse video shows the eiffel tower going dark in solidarity with aleppo, a city that once had two million residents, now reduced to ruin by years of siege and starvation. the u.s. blames syria's assad

dictatorship and its ally, russia and iran, for prolonging the fight. we have more now from holly williams. >> reporter: the buses waiting in aleppo this morning supposed to evacuate fighters and civilians from the last remaining rebel-held section of the city. [explosion] instead the ceasefire collapsed. there was shelling, more air strikes, and the buses went away empty. several thousand civilian, member, women and children, are holed up in around two square miles of territory with aleppo now nearly entirely under the syrian regime control. it's major victory for the regime after four years of fighting in the city. but it was won by indiscriminately killing civilians, which help -- with help from syrias ally, iran and russia. syria's president, bashar al

assad, called for rebels and castigated the west for troing to protect them. >> it doesn't matter what they ask. the translation of their statement is for russia, please stop the advancement of the syrian army against the terrorists. >> reporter: the u.s. has condemned the regime and its friends in russia and iran, but in five years of civil war, america has avoided a direct confrontation with the syrian regime. fearing a dangerous escalation and perhaps conflict with russia, the price of that policy has been paid by syrian civilians with their lives. the united nations human rights chief said today the bombardment of civilians in aleppo by the syrian regime and its allies is almost certainly a violation of international law, and, scott, he said it may be a war crime. >> pelley: holly williams for

us in istanbul. today the federal reserve raised a key interest rate a quarter of a point, a milestone in the recovery from the great recession. senior business correspondent anthony mason is here. anthony? >> reporter: scott, the vote was unanimous. the fed raised rates for the first time this year and only the second time since the 2008 recession. once more the fed forecasts it will hike rates three more times next year in 2017. we expect the economy will continue to perform well, said chair janet yellen, citing improving jobs numbers, unemployment is now at 4.6%, and the economy has added 180,000 jobs a month this year. but wall street was not celebrating. the dow, which had been within striking distance of 20,000, fell 118 points, snapping a post-election rally that had lasted seven straight sessions. but the dow is still up 8% since the trump victory. scott? >> pelley: anthony, what will this mean to most folks? >> well, until the trump

economic policy is in place, scott, it is really not clear. fed chair janet yellen said there has been a cloud of uncertainty hanging over that, but it is clear the fed wants to continue to raise rates by next year, the question is by how much. >> pelley: anthony mason, thank you. today one of the three survivors of the charleston church massacre told a jury she came face to face with the gunman. that man, dylann roof, is on trial for federal hate crimes, and he could face the death penalty. mark strassmann is in charleston. >> he's coming, he's come, he's coming. please! >> reporter: that 911 call from the night of the massacre was played for dylann roof's jury. >> he shot the master. he shot all the men in the church. please come right away. >> reporter: the caller was survivor polly shepperd. >> there are so many people hurt. oh, my god. >> reporter: today in federal court, the 72-year-old testified that as the faithful shut their eyes for the closing prayer,

shots rang out. she hid under a table. dead and dying people lay around her. then roof spotted her. shepperd: i was praying allowed. he told me to shut up. roof asked, "did i shoot you?" she said, "no." he said, "i'm not going to. i'm going the leave you to tell the story." roof remembered that moment in his videotaped confession to f.b.i. agents the day after the murders. >> one woman, i didn't shoot her at all. >> reporter: but while shepperd testified today, roof would not look at her. [gunfire] yesterday jurors saw this video roof took of himself firing a glock .45 pistol in his backyard. the same weapon he breakthrough to the murderous rampage at the mother emanuel church less than two months later. a medical examiner testified that each victim was shot at least five times.

suzy jackson, at 87, the oldest victim, was shot ten times. eric manning, the pastor at mother emanuel, sees deeper meaning in polly shepperd's survival. >> she stood in the face of evil and evil backed down. >> reporter: when shepperd finished testifying and left the stand, most of the people in the courtroom stood up out of respect. roof stayed seated. scott, closing arguments are set for tomorrow morning. >> pelley: mark strassmann for us. mark, thank you. this morning in newtown, connecticut, they paused for 15 minutes, exactly four years after the massacre at sandy hook elementary school. 26 people were killed then. 20 of them were first graders. this month sandy hook promise, started by family members, posted a video to turn attention toward the warning signs of a

tragedy. here's dr. jon lapook. ♪ got some news today from the radio man ♪ broke the word somber... >> reporter: it seems to be a charming story of young love. >> have a good summer. >> you too. >> reporter: two teens flirting. then... >> oh, my god. >> do you like to write? >> yes, that's what i do. >> reporter: terror. as the scenes are replayed, we realize what we've missed, a troubled student, getting bullied, posting a disturbing selfie, gesturing violently, but as the ad points out, no one noticed. >> after all the warning signs... >> reporter: students at broadview middle school in

danbury, connecticut, watched the video online. declan jakobson is an eighth grader. >> it was saying i should have been able to recognize the signals that the kid was giving. >> reporter: his school has adopted a violence prevention program, developed by sandy hook promise, called "say something." what are you taught are the warning signs? >> when people isolate themselves, when they're being bullied, a lot of times that will lead to something, or when they're obsessed with death, gun, things like that, they also teach you to talk to a trusted adult. >> reporter: psychiatrist dr. harold schwartz co-authored a 2013 report on the newtown shooter. >> risk signs appear in many people who never perpetrate violence, so what we can do that will be most effective will be to create prevention programs. >> reporter: research shows school shooters have often communicated their plans beforehand to social media, texting or conversations. >> we definitely need to destigmatize what it means to report.

for school children, we need to try to end the code of silence. >> reporter: avery marquis spoke up after seeing another student bullied. do you ever fear you might be snitching on somebody? >> no, because in the school we make it such a big thing that it's not snitching. it's saying something for everybody's safety. >> reporter: i asked some of the students if their role in trying the prevent violence was placing too much pressure on them, but they told me, no, they feel empowered by the program, appreciating what a difference they can make by focusing on somebody they might normally not even see. >> pelley: if you see something, say something. jon, thank you. coming up on the "cbs evening news," temperatures fall as quickly as the snow, and later hollywood hits chosen for immortality.
