image syria is quite proud of this evening, planes taking off from that very airfield targeted by u.s. cruise missiles last thursday night. russia which has supported syria and bashar al assad airing these images on russian tv of those jets, taking off from that same base. and there was a moment today at the white house when our correspondent asked, is there a new red line on syria? the white house answered, but then changed the answer later this afternoon. here's abc's senior white house correspondent cecilia vega. >> reporter: president trump picking up the phone to congratulate the commanding officers who launched 59 missiles into a syrian airfield. but from the looks of these images on russian state tv, that airbase is back in business, planes taking off once again. tonight, new accusations that russia was well aware of bashar al assad's chemical weapons stockpile. >> i believe that russia knew about the chemical weapons because they were operating from exactly the same base. >> reporter: this, as the white house seems to shift its red line on syria, saying it's not

just the use of chemical weapons that would provoke an american response. >> is the red line -- just to clarify, the red line for this white house chemical warfare? is conventional warfare enough to get the president to go further there than -- than this white house has gone before? >> the answer is, is that if you gas a baby, if you put a barrel bomb in to innocent people, i think you can -- you will -- you will see a response from this president. that is unacceptable. >> reporter: but assad has frequently used barrel bombs against his own people, nearly 13,000 last year alone, according to human rights groups. spicer's statement, not the only mixed message on syria from the trump administration, top officials, divided on whether or not assad should stay or go. secretary of state rex tillerson saying it's up to the syrian people. >> we believe the syrian people will lawfully be able to decide the fate of bashar al assad. >> reporter: but u.n. ambassador nikki haley all but advocating for a regime change. >> it's going to be hard to see a government that's peaceful and

stable with assad. >> reporter: the white house now seeming to echo that. >> how far is the president willing to go to see bashar al assad out of power there? >> so, just to be clear, i can't -- i don't think it's -- it's -- you can't imagine a -- a stable and peaceful syria with assad as -- as -- in charge. >> reporter: tonight, from syria, russia and iran, a joint statement, accusing the u.s. of crossing a red line with its missile strikes, warning, "from now on, we will respond to anyone, including america, if it attacks syria and crosses the red lines." it comes as secretary of state tillerson heads to moscow for talks. as exxon ceo, tillerson once shared champagne with vladimir putin. but this time, there are not yet plans for the two to meet face- face-to-face. >> and cecilia vega live with us from the white house. we heard sean spicer tell you if bashar al assad barrel bombs innocent people, which he has

often done, that president trump will respond. but tonight, the white house walking that back now? >> they are, david. in fact, they're emphasizing that quote, this is not a shift in u.s. policy. they say nothing has changed going after the assad regime for the use of barrel bombs, would mark an incredible shift in u.s. policy. david. >> all right, cecilia vega with us from the white house tonight. next this evening, we do have new reporting on the deadly attacks just as the christian holy week begins. suicide bombers targeting palm sunday services at two churches. this video right here showing one of the bombers being directed to go through a metal detector to get inside a church in egypt, instead stepping back towards two police and blowing himself up. isis taking responsibility with a new warning that there's more to come. here's abc's brian ross. >> reporter: the choir was singing when a bomb hidden under

as pope francis sunday deplored the isis church attacks, security officials at the vatican and churches around the world were seeing what they could do to enhance the already-high security for the coming holy week. >> just horrific. brian ross with us tonight. despite that threat from isis the pope still plans to travel to egypt? >> yes, david, that trip is still on. the vatican says the pope's mission to be beside his brothers in egypt at this time of difficulty. >> brian ross, thank you. we're also following breaking news tonight coming in from the alabama statehouse. governor robert bentley, caught in a sex scandal there, just a short time ago now resigning just as an impeachment hearing was getting under way. abc's steve osunsami is in montgomery tonight. >> reporter: this awkward-looking photo is a shameful ending tonight for a governor who's also a deacon at his baptist church and recently argued that marriage is a holy union between one man and one woman. >> i have decided it's time for me to step down as alabama's

governor. >> reporter: alabama governor robert bentley didn't just have one woman, he had two, the campaign aide who authorities say he illegally paid with money that he strong-armed from donors, and the wife who got even when she recorded cell phone conversations with his girlfriend, and then turned them over to police. >> baby, let me tell you what we're going to have to do. >> reporter: his alleged mistress, rebekah mason, is a campaign consultant and a former beauty pagent winner 30 years his junior. >> we've been very betrayed by robert bentley and he needs to go off into the sunset. >> reporter: the governor is pleading guilty to two misdemeanor campaign finance violations. he'll have to pay back the money he misused. but he'll avoid real jail time. david. >> steve osunsami with the late developments for us. next to that moment of victory today for president trump. his supreme court nominee now on
