The United States government provided information to Russia that prevented a terror attack in St. Petersberg on Saturday, according to officials from the two countries.

The statement from the White House said, “Both leaders agreed that this serves as an example of the positive things that can occur when our countries work together,” but news analyst Charlie Sennott was wary of the public discussion of the collaboration.

“It’s bizarre to have a president of the United States sharing that publicly, first of all, in a kind of bromance with Putin, who is an adversary of the United States, and [leads] a ... country that interfered with our democratic process and our election,” said Sennott on Boston Public Radio today.

Sennott said while he believes in diplomacy, a “warm and fuzzy relationship” is cause for concern, given Russia’s attempted influence over the American presidential election.

“Given what’s happened, it's worth paying very close attention to how President Trump views his relationship with Putin in relation to, particularly, technology and security and the CIA,” said Sennott.

The attack was planned for Saturday in Russia, and the White House and the Kremlin confirmed that Putin phoned Trump to thank him for the information provided by the CIA.

Sunday was the second time the two leaders had spoken in a week, with the first call happening on Thursday. That call was related to relations with North Korea.

“We keep getting this relationship between President Trump and Putin,” Sennott said. “It’s worrisome, it's disconcerting, and sometimes it's just really strange.”
