Former President Trump, addressing reporters on his way into court, defended the way payments were made to his former attorney Michael Cohen, pushing back on the crux of the DA's case that they were improperly labeled as legal expenses.

"I was paying a lawyer and I marked it down as a legal expense, some accountant," Trump said. "I didn't know. That's exactly what it was."

Manhattan District Attorney Alvin Bragg has accused Trump of improperly labeling the money as legal expenses to Cohen in order to hide that the funds were to repay hush money paid to Stormy Daniels to boost Trump's electoral prospects.

"Legal expense -- that's what you're supposed to call it," Trump said.

"This is a trial that should never happen, it should have been thrown out," he said.

Former President Trump has arrived at the courthouse for the second day of jury selection.

Unlike Monday when a small group of supporters and protesters greeted the former president, there were essentially none at the courthouse this morning.

He again railed on social media against the limited gag order that prevents him from targeting witnesses and others associated with the case.

"I want to speak, or at least be able to respond," Trump wrote on his social media platform, attacking Judge Juan Merchan and again claiming the trial is "election interference."

Jury selection will continue today on Day 2 of former President Trump's hush money trial.

Attorneys on Monday began the process of narrowing down the first group of 96 juror prospects, but none were seated by the end of the day.

Attorneys today will continue their questioning of the remaining juror prospects from that group, with a new group of prospective jurors scheduled to arrive in court this morning.

Exiting court after a lengthy day of proceedings, former President Trump complained about the scheduling conflicts created by his criminal trial, including conflicts with his presidential campaign, his plans to attend Supreme Court oral arguments, and potentially his son Barron's high school graduation.

"Now I can't go to my son's graduation," Trump said. "I can't go to the United States Supreme Court. I'm not in Georgia or Florida or North Carolina campaigning like I should be," Trump told reporters outside court.

Trump repeated his past complaints about the fairness of the trial, saying he has a "real problem" with Judge Merchan.

"It's a scam, it's a political witch hunt," Trump said. "We're not going to be given a fair trial."

Former National Enquirer publisher David Pecker testified that he believed Donald Trump had knowledge about the $150,000 contract to buy Karen McDougal's silence regarding an alleged year-long affair.

"Do you know if anyone else besides Michael Cohen had any knowledge of this contract?" prosecutor Joshua Steinglass asked.

"Yes, I believe Donald Trump did," Pecker responded.

"Was your principal purpose to suppress the story to prevent it from influencing the election?" Steinglass asked.

"Yes," Pecker said.

"Were you aware that expenditures by corporations made for the purpose of influencing an election made in coordination with or at the request of a candidate or campaign were unlawful?" Steinglass asked.

Pecker said he was aware and confirmed that the Enquirer's parent company, AMI, never reported the payment to the Federal Election Commission.

"We purchased the story so it wouldn't be published by any other organization," Pecker said.

"Why did you not want it to be published by any other organization?" Steinglass asked.

"We didn't want the story to embarrass Mr. Trump or embarrass or hurt the campaign," Pecker said.

"Who is we?" Steinglass followed up.

"Myself and Michael Cohen," Pecker said.

According to Pecker, AMI agreed to the $150,000 payment on the promise that Donald Trump or the Trump Organization would reimburse AMI for the payment. He frequently followed up with Cohen about the reimbursement and got a similar answer from Cohen.

"Why are you worried? I am your friend. The boss will take care of it," Pecker said about Cohen's response.
