A Florida congresswoman is alleging that President Trump told the widow of a slain U.S. soldier that “he knew what he signed up for” when he enlisted in the military. According to Rep. Frederica Wilson (D-FL), Trump made the remark to the widow of Army Sgt. La David Johnson, who was killed this month during an ambush on Green Berets in Niger. “Yes, he said it,” Wilson said. “It’s so insensitive. He should have not have said that. He shouldn’t have said it.” Wilson was with Myeshia Johnson, the soldier’s widow, in a limousine at the time of the call and overheard it over speaker phone, The Washington Post reported. Wilson said she wanted to “curse him out” for making Johnson break down and cry. “He was talking off the cuff, saying the same thing over and over again,” Wilson was quoted as saying. Trump tweeted a response Wednesday morning disputing Wilson’s account. He wrote, “Democrat Congresswoman totally fabricated what I said to the wife of a soldier who died in action (and I have proof). Sad!” On Thursday night, White House officials would not confirm or deny the alleged comment.
