Donald Trump's former personal attorney, Michael Cohen, speaking on ABC's "Good Morning America" Friday, said he was "absolutely" prepared for cross-examination in a potential trial after completing his testimony this week before a Manhattan grand jury mulling charges against Trump.

"I was working for a man who ultimately became president of the United States, and, yes, there are things that we did that were wrong -- for example, the hush-money payment -- but I never expected that democracy would be on the line as a direct result of the former president," Cohen told ABC News Anchor George Stephanopoulos.

Trump's one-time fixer said he's not worried about allies of Trump attacking his testimony.

"The facts are the facts. The truth is the truth and the truth will always rise so I'm not worried about anything that they want to come at me with," he said.

Cohen did not divulge what prosecutors, investigating the 2016 payment made to adult film actress Stormy Daniels, asked him specifically after he met with them twice this week, but said, in his view, they have enough evidence to indict and convict the former president.

"I promise you and I promise the American people that all the information that is needed in order to create the indictment to get a prosecution and a conviction is in the hands of the district attorney," Cohen said.

Stephanopoulos asked Cohen his biggest regret, and he said it was accepting a job from Trump in 2007.

"That's my biggest regret. There was absolutely no reason for it. I didn't need to work for him and I probably shouldn't have. I should have listened to my wife, my daughter, my son and not accepted the job, but I did and, yeah, it's cost me a lot. It's cost my family a lot. Our happiness, finances, my law license," he said. "But most importantly, as I said to you almost five years ago today that my wife, my daughter, my son and my country have my first loyalty and they always will."

Stephanopoulos asked, "Do you think justice will be served?"

"I know it will be," Cohen replied.

Cohen tweeted a reminder ahead of the interview that five years ago he told Stephanopoulos that⁩ his first loyalty was not to Trump but to his family and country, promising to discuss how he's adhered to the words since.
