Michael Cohen, President Donald Trump’s former personal lawyer, will make extraordinary claims about a man whom he calls a “racist,” a “conman” and a “cheat,” according a copy of Cohen’s statement obtained by Roll Call.

The statement also indicates that Cohen plans to bring documents to his hearing before the House Oversight Committee on Wednesday that provide, he will claim, “irrefutable” proof that his testimony is “accurate and truthful.”

If the documents materialize, they potentially could have much more impact than critical comments about Trump by Cohen, a now-disbarred lawyer who has pleaded guilty to lying to Congress.

Those documents include a copy of a check that Cohen alleges Trump wrote from his personal bank account after he became president to reimburse Cohen for the hush money payments he made to pornographic film actress Stephanie Clifford, known by her stage name of Stormy Daniels, in the weeks leading up to the 2016 election.
