Former President Donald Trump took the witness stand in a New York courtroom Monday, testifying in a high-stakes $250 million civil fraud case that could lead to the dismantling of his sprawling business empire.

Trump was sworn in shortly after the court was called in session and was soon ranting about the lawyer questioning him from state Attorney General Letitia James’ office.

“You and every other Democrat … coming after me from 15 different sides … all haters,” Trump complained to his questioner, Kevin Wallace.

Trump is testifying before state Supreme Court Judge Arthur Engoron — who he has repeatedly mocked on his social media platform, Truth Social. In recent days, he has posted that Engoron is “crazy, totally unhinged, and dangerous" and a “Trump hating judge” who is a “disgrace to the legal profession.” In one post, he said Engoron “should be thrown off the ‘Bench’ as a giant Embarrassment to New York State!”

Trump wasted little time mixing it up with the judge from the stand as well. After the judge chided him for giving non-responsive answers, Trump said “The judge will rule against me because he will always rule against me.” The judge said that comment was not true, and asked Trump to “please answer the question. You can attack me all you want but just answer the question.” After more tangents, he told Trump’s lawyers “I beseech you to control” him. “This is not a political rally,” he said.
