'He's got documents': Michael Cohen will show 'detailed, sordid and chilling' evidence against Trump

Michael Cohen intends to address his credibility issues during his highly anticipated testimony before lawmakers.

The former Trump Organization attorney has pleaded guilty to lying during previous congressional testimony, before cutting a cooperation agreement with investigators, and NBC News national security correspondent Ken Dilanian told MSNBC's "Morning Joe" that Cohen has a plan to address those issues.

"He's expected to address, first of all, his lies to those (congressional) committees on the timing of the Trump Tower and Moscow deal, the fact that it was going on much longer than he admitted in public and much longer than Donald Trump acknowledged," Dilanian said.

Cohen's plea agreement details the president's lies about his dealings with Russia during the 2016 campaign, but he's not allowed to address those issues before Congress because special counsel Robert Mueller's investigation is still pending.

"We could have an absolutely dramatic and riveting performance by Michael Cohen," Dilanian said. "While he's not allowed to talk about the Russia investigation when he appears before the House Oversight Committee on Wednesday, he's going to talk about those hush money payments to women."

The committee was also expected to question Cohen about Trump's compliance with campaign finance and tax laws, potential conflicts of interest with his family business, Trump Organization business practices.

"I'm told Cohen has been prepping with this for a long time, and he knows he's got credibility issues, so he's coming with documents," Dilanian said, "and he's got very detailed, sordid and, what (attorney) Lanny Davis has described as chilling stories of what how the president conducts himself behind closed doors."

"We shouldn't underestimate how powerful seeing a Trump insider who has been with Donald Trump for more than 10 years telling these stories before the glare of the television lights," he added.
