Rep. Adam Schiff (D-CA), the ranking Democrat on the House Intelligence Committee, accused the White House of interfering" in the investigation of Russian meddling in the 2016 election.
"Now in an effort to justify the unjustifiable, he is now interfering in this investigation," said Schiff, referring to Trump's unproven allegation that his campaign was "wiretapped" by the Obama administration.
Nunes said the intercepted messages included foreigners talking to foreigners and did not involve Russia. He later apologized, according to other Democrats on the committee, for sharing the information with the White House before informing the full committee.
Schiff was asked about the new information brought up by Nunes on the alleged "unmasking" of Trump associates' names in intercepted conversations of foreigners.
Schiff said he still has not seen the documents referenced by Nunes, but believes they are a "subset of what we requested from the NSA."
He said the incidental collection, perhaps targeted at foreign spies, may have picked up mentions of Trump or his associates.
"That would be considered incidental collection ... not targeted at the president. So no defense for the president. Not a full validation or vindication of the president, not a partial validation, a zero validation of the president," said Schiff.
