The former president received a second fine for violating a gag order prohibiting him from speaking about witnesses, jurors, court staff and their families. Trump is trying to appeal the gag order.
Judge Juan Merchan previously issued a gag order that specifically bars Trump from making or directing others to make public statements about potential jurors, court staff or family members of staff.
A court filing said the bond was provided by Knight Insurance, a California-based company. The move ensures that New York Attorney General Letitia James can't seize Trump's assets related to the case.
The appeals court ruling would allow Trump to make public statements about the special counsel in the case, Jack Smith, but not other prosecutors, court staffers or their family members.
Lawyers for the former president and the special counsel team argued before a federal appeals court about the scope of a gag order lodged against him. The court gave no timetable for a ruling.
His testimony is expected to be followed by his younger brother Eric, another vice president of the family's landmark business. Both, alongside their father, are defendants in the trial.
Judge Arthur Engoron issued the order on former President Donald Trump and his legal team on Tuesday as a result of a social media post featuring one of the judge's staffers.
Hennepin County District Judge Peter Cahill lifted the order on Tuesday, after opposition from attorneys for the defendants and a number of media organizations.
