Former president Donald Trump posted a $175 million bond for his New York State civil fraud case Monday evening through an insurance company.

Trump posted the bond backed by the California-based Knight Speciality Insurance Company, kick-starting the appeals process against the $355 million civil fraud judgment imposed by New York judge Arthur Engoron last month. Trump is on the hook for more than $450 million because he is mandated to pay interest on top of Engoron’s judgment.

Last week, an appellate court granted Trump a ten-day extension to pay the reduced $175 million bond after it appeared Trump would not be able to post the original bond on time. His social-media company Truth Social went public on Tuesday, and shares immediately soared, giving Trump a multibillion-dollar boost to his net worth, despite the company’s poor financials.

“Bond filed. We look forward to vindicating our rights on appeal,” Trump’s son Eric, a top executive overseeing his business empire, said on X.

At the same time, Manhattan judge Juan Merchan expanded his gag order against Trump on Monday night to prevent Trump from criticizing the judge’s relatives after Trump went after them online. Merchan is overseeing the criminal case brought against Trump in Manhattan related to the “hush money” payment sent by his former attorney, Michael Cohen, to porn actress Stormy Daniels ahead of the 2016 presidential election. Daniels has alleged that she and Trump had an extramarital affair, a claim the former president denies.

Merchan issued his initial gag order on March 26 ahead of Trump’s criminal trial in Manhattan for allegedly falsifying business records connected to the payment to Daniels. The initial gag order prevented Trump from criticizing potential witnesses and jurors in the upcoming case, with jury selection set to begin on April 15.
