cnn's priscilla alvarez is in los angeles where president biden is attending the final day of the summit of americas. hi there, priscilla. so the white house is acknowledging the pain americans are feeling right now, but they're also shifting blame for this rapid rise in inflation we're seeing. >> reporter: well, that's right. and yesterday here in los angeles president biden spoke at a port in which he said that lowering inflation is a top economic priority. and this came, as you heard from christine, as the consumer price index showed that the record gas prices drove inflation to 8.6% and that food prices rose 11.9%. that has been the reality for the biden administration as americans feel that in their pockets and in their wallets. now biden did blame russian president vladimir putin and his war in ukraine for the soaring prices. take a listen to what he said -- >> make no mistake about it, i understand inflation is a real challenge to american families. today's inflation report confirmed what americans already know -- putin's price hike is hitting america hard. gas prices at the pump,

cnn's priscilla alvarez is live in texas with the very latest on this. priscilla, what is the very late? >> reporter: well, kate, that death toll has gone up to 50 as you mentioned. an official tells me three more died on the way to the hospital. this may be the deadliest smuggling incident. now, yesterday, authority has received a call from someone in the area who had heard a cry for help. and that person was alerted then to the truck where they found deceased individuals. authorities responding to the scene said that the people they found had suffered from heat exhaustion. and from heatstroke. authorities said that they were hot to the touch and too weak to get out of the truck. remember, we are in texas where there's sweltering heat here. and the temperatures have been going up to the triple digits. now, authorities here have been calling this a tragic incident. take a listen to what the mayor of san antonio said this morning. >> this is probably the worst tragedy in terms of migrant -- migration that i know at least in recent history. and the people

priscilla alvarez is live in texas with more for us on all of this. what is the impact of this decision? >> reporter: kate, it's not immediately clear how quickly this decision will go into effect because, as you heard from jessica, there are additional proceedings that have to happen. but it is nonetheless a victory for the biden administration which had criticized this policy and said it came at a steep human cost. this had been an unprecedented policy put in place in 2019 because it required migrants seeking asylum to wait in mexico until their immigration court date in the u.s. that was different from what had happened for years, which is that migrants could wait for those hearings in the united states, being released in the united states, or while they were detained. since 2019, more than 68,000 migrants had been subject to this policy. just over the last hour, kate, i have been getting so many messages from immigration attorneys and advocates who are celebrating this. for years they had said that this policy had put migrants in dangerous and squ

. >>> let's go to priscilla alvarez. she's traveling with the president at the summit of americas in los angeles this morning. good to see you. talk to us about what else the president said because putin was not his only target. >> reporter: that's right. the president also said that this was an economic priority, that is lowering inflation, and he also called out oil and gas companies, urging them not to take excessive profit, and he called on congress to pass a bill to lower or cut shipping costs to therefore lower the price of goods. but to your point earlier, the president did point to putin calling it putin's price hike as americans grapple with soaring prices. and that is something that he has continued to do over the last few weeks as the administration grapples with the reality that gas continues to go up. in fact, the latest consumer price index showed us that the record gas prices drove inflation to 8.6%, and food prices rose 11.9%. the white house conceding that this is uncomfortably high. that is inflation. b
