House Intelligence Chairman Devin Nunes said Wednesday that the U.S. intelligence community collected multiple conversations involving members of Donald Trump’s transition team after he won the election last year.

He said the intercepts he’s seen appear to be legal and weren’t targeted at the transition team or related to Russia. But he said he was troubled by the collection — which he said was part of unrelated foreign surveillance — and the fact that the intelligence community reported the names of transition team members internally.

“I’m actually alarmed by it,” Nunes, a California Republican, told reporters at the Capitol. “Details with little or no apparent foreign intelligence value were widely disseminated in an intelligence community report,” he said. He said he didn’t know if Trump’s “own communications were intercepted.”
