President Trump’s former fixer Michael Cohen, who is scheduled to testify before Congress at 10 a.m. ET today, will accuse Trump in a congressional hearing of being a racist and a conman in testimony that will offer a rare televised glimpse into the cloud of scandals that have haunted Trump’s presidency.

According to testimony released ahead of his appearance, Cohen will say Trump knew that his former political adviser Roger Stone was aware of pending releases of stolen emails intended to damage Hillary Cinton’s presidential campaign.

“Mr. Stone told Mr. Trump that he had just gotten off the phone with Julian Assange and that Mr. Assange told Mr. Stone that, within a couple of days, there would be a massive dump of emails that would damage Hillary Clinton’s campaign,” Cohen will say, according to his prepared testimony.

Trump responded, according to Cohen: “Wouldn’t that be great.”

The disclosure will revive speculation that the President colluded with representatives of Russia to interfere in the 2016 election, which evolved into an effort by Moscow to help Trump win in his duel against Clinton.

Why this matters: Cohen’s allegations, if true, would amount to the first time anyone with direct knowledge of the situation has said the President had advance knowledge of the WikiLeaks dump of Clinton emails.
