New York Attorney General Letitia James’ office on Wednesday requested a state appeals court require former President Donald Trump to post a bond that fully covers a $454 million civil fraud judgment against him.

In court documents released on Monday, Trump’s legal team argued that securing a bond in the full amount would be “a practical impossibility” for the former president. His attorneys have previously asked if Trump could pay a portion of the amount, $100 million, while he appeals the ruling.

“As far as the Court can infer, sureties may have refused to accept defendants’ specific holdings as collateral because using Mr. Trump’s real estate will generally need ‘a property appraisal’ and his holdings are not nearly as valuable as defendants claim,” Fan wrote.
