Former President Trump has reclaimed his seat at the defendant's table, Judge Juan Merchan is back on the bench -- and the second day of the criminal trial of the former president is underway.

Trump greeted court officers upon arrival, mouthing to one, "How are you?" as he made his way down the aisle accompanied by lawyers Todd Blanche, Susan Necheles and Emil Bove.

Trump is once again seated between Blanche and Bove.

The three men appeared to be in and out of conversation as they awaited the judge, with Trump periodically looking down at the desk or at the monitor in front of him.

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.

The first six jurors selected to serve in Donald Trump's criminal hush money trial represent a diverse cross-section of New York City, according to their biographical information. Here's a brief sketch of each juror, whose identities are being kept private for security reasons.

Juror No. 1 is a middle-aged salesman who immigrated to the United States from Ireland. He lives in West Harlem and said he normally gets his news from the New York Times, Daily Mail, Fox News and MSNBC. In his spare time, he said he enjoys doing "anything outdoorsy."

Juror No. 2 works as an oncology nurse at Memorial Sloan Kettering. She lives with her fiancé and enjoys taking her dog for walks in the park. She said she gets her news from The New York Times, CNN, Google, and Facebook.

Juror 3 is a corporate attorney who moved to New York from Oregon five years ago. He has worked at two major white-shoe law firms in New York. He said he normally gets his news from The New York Times, Wall Street Journal, and Google. In his spare time, he said he enjoys hiking and running.

Juror No. 4 said he finds the former president to be "fascinating and mysterious." Originally from Puerto Rico, he has lived in the Lower East Side for the last 40 years. He is a self-employed IT consultant who attended one year of college and has been "married for a long time." He normally gets his news from the Daily News, The New York Times, Google.

Juror No. 5 was the only potential juror who raised her hand when lawyers asked if they had ever heard of Trump's other criminal cases. A life-long New Yorker, she currently works as an ELA teacher in a charter school and lives in Harlem. She normally gets her news from Google and TikTok but said that she "doesn't really care for the news."
