Florida congresswoman U.S. Rep. Frederica Wilson (D-Fla.) said President Donald Trump told the pregnant widow of a fallen soldier he “must’ve known what he signed up for.”

While Trump has since denied the claims, the mother of the soldier who was recently killed while on duty in Niger verified Wilson’s account of the conversation between her daughter-in-law and Trump. The congresswoman claimed she was in a car with widow Myeshia Johnson when she overheard the president’s call about her late husband, Sgt. La David Johnson. Johnson died on Oct. 4.

“Sarcastically, [Trump] said: ‘But, you know, he must’ve known what he signed up for,'” Wilson told NBC Miami. “How could you say that to a grieving widow? … I couldn’t believe, and he said it more than once. This man has no feelings for anyone. This is a young woman with child.”

“Everyone knows when you go to war, you could possibly not come back alive, but you don’t remind a grieving widow of that,” she continued. “That’s so insensitive.”

On Wednesday, Jones’ mother, Cowanda Jones-Johnson, told the Associated Press and Washington Post that Wilson’s recollection of the conversation was correct.

“If you are the leader of the free world, if you are president of the United States and you want to convey sympathy to a grieving family, a grieving widow, you choose your words carefully,” Wilson said. “And everyone knows that Donald Trump does not choose his words carefully.”

“She was crying for the whole time,” Wilson said of the widow. “And the worst part of it: When he hung up, you know what she turned to me and said? She said he didn’t even remember his name.”
