PALM BEACH, Fla. — Former president Donald Trump escalated his attacks on prosecutors at a private luncheon here Saturday, referring to special counsel Jack Smith with an expletive and accusing Democrats of “running a Gestapo administration,” according to audio provided by a Republican donor.

He called Smith — who is prosecuting federal cases involving Trump’s handling of classified documents and his role in the Jan. 6, 2021, attack on the Capitol — a “f—ing a–hole.” He continued to mock another prosecutor, District Attorney Fani T. Willis (D) of Georgia’s Fulton County, for her past relationship with former special prosecutor Nathan Wade, calling her “Mrs. Wade” and “a real beauty.”
