President Donald Trump reportedly told the widow of 25-year-old U.S. Army Sergeant La David Johnson, that her late husband "knew what he was signing up for," when he joined the military. According to Rep. Frederica Wilson, Trump made the remark to the pregnant wife of the late veteran, who was killed in Niger, during a phone call. Johnson is the mother of two other children, a two-year-old son and a six-year-old daughter. Wilson told an NBC affiliate that Trump initially sounded like he was speaking "sarcastically" and that "he said it more than once." The veteran was one of four U.S. Special Operations soldiers killed in an ambush in Niger on Oct 4.
