BUFFALO, N.Y. -- Michael Caputo, a Western New York political adviser and former aide to Donald Trump's presidential campaign, has been contacted by the FBI regarding the special counsel's investigation into Russian interference in the 2016 election, according to sources.
NBC News was first to report the development, which comes on the same day the President seemed to confirm on Twitter that he is personally under criminal investigation for possible obstruction of justice as part of that same probe.
Robert Mueller has been named the special counsel.
Caputo referred questions to his attorney, Dennis Vacco, who denied that the FBI or special counsel has reached out.
Caputo said on a radio show this week that he would speak with the FBI or special counsel if they made such a request.
"I'll be part of the reason why they understand that none of this went on," Caputo said on Fox News Radio.
He has also said he will cooperate with ongoing investigations in Congress.
Sources say the FBI wants to question Caputo before he speaks to the House Intelligence Committee, and that hearing could happen as early as next month.
Caputo has said he'll only speak voluntarily if it's in open session.
Earlier this month, Caputo told 2 On Your Side's Michael Wooten that he has nothing to hide and looks forward to testifying.
"I think, in the end, the good men and women of the FBI will prove that there's no Russian collusion," Caputo said from his East Aurora office. "I'm quite certain that I did no colluding."
