figure out what putin's, quote, offramp is to get out of this conflict. this is a question being asked by leaders around the world. >> reporter: president biden seemed puerplexed. he asked aloud to this group of donors, how is putin going to get out of this loss of power given the war there? he doesn't necessarily see an offramp. sit worth repeating u.s. officials are saying of this nuclear threat, as of tonight, they see no change this russia's nuclear power and the u.s. government is not changing its. >> cecilia vega leading us off on a friday night. thank you. mayor eric adams declaring a state of emergency for the humanitarian crisis. more than 17,000 migrants since april. busses arriving every day. eight busses yesterday, nine more, including this one, today. the city preparing to build a tent city and negotiating with a

the directly deny that donald trump still has more government records, but instead went on to criticize the fbi and the department of justice for, quote, perpetuating witch-hunt after witch-hunt. but again, david, in that written statement from trump's spokesperson, no denial of this. >> no firm denial. thank you, jon. we turn next to the investigation into president biden's son.
