A lawyer for Paul Manafort, the former Trump campaign chairman, reached out to the House Intelligence Committee to volunteer his testimony before the panel, Rep. Devin Nunes (R-CA) said during a Friday press conference. Manafort has offered to be “voluntarily interviewed” by the committee, but whether it will happen in either open or closed session has not yet been determined, Nunes noted. “We thank Mr. Manafort for volunteering and encourage others with knowledge of these issues” to do the same. Manafort is a key part of the federal probe into Trump’s campaign team allegedly coordinating with Russian officials to interefere in the 2016 U.S. election. He made headlines this week for his former Russian clients and financial history in Ukraine. Federal investigators are in the middle of a separate investigation into Manafort’s banking history.
