"One thing I know a lot about is the legal definition of fraud," Justice Arthur Engeron said as he gaveled court into session prior to the start of opening statements.

Engoron opened the proceedings after allowing cameras in to document the scene in the courtroom: Trump, arms folded, flanked by his legal team; Engeron on the bench; and throngs of reporters and spectators in the gallery.

"I've promised to do my best despite my lame attempts at humor," Engeron said in a brief opening statement. "I take my job very seriously."

The trial is expected to last through Dec. 22, Engeron said, and suggested he would attempt to keep a low profile after today.

"For the next three months, I hope the only words I will mutter are 'Sustained,' 'Overruled,' and 'Let's take a 10-minute break,'" he said.

Opening statements are underway in former President Trump's $250 million fraud trial.

Trump is seated between his attorneys Clifford Robert, Alina Habba and Christopher Kise.

Trump and his co-defendants face a bench trial, meaning that the sole arbiter of the case is Judge Arthur Engoron instead of a jury.

Former President Trump has taken a seat in the courtroom for the start of the trial.

"The crime is against me," he told reporters outside the courtroom before he made his way inside.

He denounced the case in now-familiar terms, criticizing state Attorney General Letitia James as she sat inside the courtroom.

Trump also accused Judge Arthur Engoron of failing to account for the full value of his real estate portfolio, asserting his Mar-a-Lago estate is worth "50 to 100 times more" than the judge's decision for partial summary judgment said last week.

"We have other properties, the same thing. So he devalued everything," Trump said. "We have among the greatest properties in the world. and I have to go through this for political reasons."

Engoron decided Trump's statements of financial condition were fraudulent, but Trump said, "We have a clause in the contract that says, essentially, buyer beware."

Former President Trump, speaking to reporters on his arrival at the lower Manhattan courthouse, said the trial is a witch hunt resulting from his standing in the presidential polls.

"This is a continuation of the greatest political witch hunt of all time," he told reporters outside the courtroom.

Trump said he is innocent of the accusations and that his portfolio has a much higher value than what the attorney general alleges.

Defense attorney Chris Kise requested that Judge Engoron again reconsider his decision to fine Donald Trump $10,000 for violating the case's limited gag order yesterday, offering a broader criticism of the gag order based on First Amendment grounds.

"This is open, public, and the defendant has a First Amendment right to comment on what he sees and perceives as a potential source of bias," Kise said.

Like yesterday, Kise maintained that Trump was referring to Michael Cohen, rather than the judge's law clerk, during his hallway statement in which he said the judge has a "person who is very partisan sitting alongside of him." Trump attested to this on the stand yesterday, though Engoron found that Trump was "not credible."

"The review of the statement does not support the sanction," Kise said.

Even if Trump was referring to the clerk, Kise made a broader argument that the gag order itself was "constitutionally infirm," considering Trump is the "leading candidate" for the presidency.

"I don't think that the order survives constitutional scrutiny," Kise said.

State attorney Andrew Amer argued in support of the gag order, which he said was narrowly limited to withstand constitutional scrutiny.

"A federal judge in D.C. has issued a similar order to protect herself," Amer added, referring to a ruling in Trump's election interference case.

Judge Engoron said he would reconsider the fine but stood by his gag order.
