House investigators release more impeachment transcripts

House Democrats released new transcripts of Trump officials' testimony Friday as they pushed their impeachment inquiry toward next week's public hearings.

Investigators in the inquiry into President Donald Trump's actions released hundreds of pages of testimony from Fiona Hill, a former White House Russia adviser, and Lt. Col. Alexander Vindman, an Army officer assigned to the National Security Council. Both testified about their concerns as Trump pressed Ukraine to investigate Democrats.

Vindman alerted superiors on two occasions, including after he listened to the July call in which Trump personally appealed to Ukrainian President Volodymyr Zelenskiy to investigate political rival Joe Biden and the outlier theory of a Ukrainian role in the 2016 U.S. presidential election.

A whistleblower's complaint about that call triggered the impeachment probe.

Trump insisted earlier Friday he has not been damaged by testimony detailing efforts by him and his administration to pressure Ukraine.

Speaking to reporters as he left on a campaign trip to Atlanta, Trump said he was "not concerned about anything" that has been disclosed so far.

House investigators are releasing key transcripts from days of closed-door interviews in the impeachment inquiry as they prepare for public sessions with witnesses next week.
