Transcript for Michael Cohen returns to Capitol Hill

Also in Washington, Michael Cohen back on capitol hill today for closed door testimony before the house intelligence committee. As president trump labels the congressional investigations a big fat fishing expedition and his lawyers refuse to turn over documents detailing how the president pushed for his son-in-law, Jared Kushner's security clearance over objections from intelligence officials.
