Rep. Alcee Hastings, a Florida Democrat with a reputation for riling Republicans and weathering numerous controversies, entertained a crowd Sunday with a joke about President Donald Trump falling into the Potomac.

The joke, at a rally sponsored by 16 of South Florida’s Broward County Democratic clubs, revolved around the difference between a “crisis” and a “catastrophe.”

A crisis, he said, is if the Trump falls into the Potomac River in the nation’s capital, according to an account in the Florida Sun Sentinel.

A catastrophe, Hastings said, would be if “anybody saves his ass.”

The quip was one of many Hastings aimed at the president during the event, which he emceed. It was attended by four of the five Democratic candidates for governor and Democratic U.S. Sen. Bill Nelson, who is seeking re-election. Nelson and the gubernatorial candidates had left by the time Hastings delivered his one-liner, the newspaper reported.
