Ms. Pirro, the U.S. attorney for the District of Columbia, disclosing felony vandalism charges against Mr. Hearn for touching the lining of the pool in front of the Lincoln Memorial. She added: “We will prove beyond a reasonable doubt that Hearn willfully destroyed property.”

In the process, intentionally or not, she skated perilously close to contradicting Mr. Trump — and he noticed.
