President Trump’s longtime adviser Roger Stone said Wednesday that Michael Cohen’s planned statement before the House Oversight Committee is “untrue,” according to ABC News.

In prepared testimony to the committee, Cohen, the president’s onetime lawyer and “fixer,” lays out a stunning string of allegations about Trump.

Among his explosive allegations, Cohen will say that the president was aware that Stone was working with Julian Assange and WikiLeaks about the release of emails belonging to Democratic presidential candidate Hillary Clinton and the Democratic National Committee.

Stone has pleaded not guilty to charges of lying in the feds’ probe into Russian election meddling and possible collusion with the Trump campaign.
