The House Intelligence Committee has issued subpoenas for documents and testimony from former national security adviser Michael Flynn and former Trump campaign aide Richard Gates.
"As part of our oversight work, the House Intelligence Committee is continuing to examine the deep counterintelligence concerns raised in Special Counsel Mueller's report, and that requires speaking directly with the fact witnesses," the committee's chairman, Rep. Adam Schiff (D-Calif.), said in a statement on Thursday.
Schiff noted that both Flynn and Gates cooperated extensively with special counsel Robert Mueller as part of his investigation into Russian interference in the 2016 presidential election, but said that they have so far “refused to cooperate fully with Congress.”
In a Wednesday letter, Schiff demanded that Flynn, who worked on President Trump's campaign and briefly in the administration, provide “documents and other materials” by June 26 and appear before the committee for sworn testimony on July 10.
