Premise: ADDS TRUMP'S RESPONSE TO REP. WILSON - In this Tuesday, Oct. 17, 2017, frame from video, Myeshia Johnson cries over the casket of her husband, Sgt. La David Johnson, who was killed in an ambush in Niger, upon his body's arrival in Miami. President Donald Trump told the widow that her husband "knew what he signed up for," according to Rep. Frederica Wilson, who said she heard part of the conversation on speakerphone. In a Wednesday morning tweet, Trump said Wilson's description of the call was "fabricated." (WPLG via AP)
