Sen. John Fetterman (D-PA) pushed back against members of his own party for mocking President Donald Trump’s ceasefire deal with Iran on Wednesday.

A common saying Trump’s opponents have been mocking him with is the word “TACO,” an acronym for “Trump always chickens out.” This taunt was used when Trump reached a two-week ceasefire deal with Iran hours after the president threatened that “a whole civilization will die” if a deal was not reached, with late-night host Jimmy Kimmel saying Tuesday marked the “Taco Tuesday of all Taco Tuesdays.”
