Vladimir Putin

The former FBI agent whom President Trump once accused of treason is out with a new book that claims Trump is a threat to national security.

Peter Strzok, former deputy of the FBI counterintelligence division, was at the heart of investigations into Hillary Clinton's email server and the 2016 Trump campaign's ties to Russia.

Republican Ohio Governor John Kasich says he would not have called Russian President Vladimir Putin to congratulate him on his election win, as President Trump did recently.
