"The special counsel stated emphatically that the information that I gave to them was credible," Cohen said Friday.

"There's a substantial amount of information that they possess that corroborates the fact that I am telling the truth," he continued.

Cohen went on in the interview to say that he was "done" protecting Trump, his former boss, from claims that the president was involved in illegal campaign contributions related to payouts Cohen made to Stormy Daniel and Karen McDougal, two women who threatened to tell their stories of affairs with the president in 2016.

"I'm done with the lying. I'm done being loyal to President Trump," Cohen said. "And my first loyalty belongs to my wife, my daughter, and this country."

The president has dismissed Cohen's claims that he directed the payments in recent days, arguing that the contributions were not criminal in nature.

"They put that on to embarrass me," Trump said of the campaign finance-related charges on Thursday.

Trump has also directly attacked Cohen, calling him a "weak" person and accusing Cohen of lying about Trump's business dealings in Moscow to secure a better deal.

“He's a weak person and what he's trying to do is get a reduced sentence,” Trump told reporters. ”So, he's lying about a project that everybody knew about.”
