The widow of a U.S. Army sergeant killed in Niger this month said on Monday that President Donald Trump had "made me cry even worse" in a condolence telephone call when he said her husband "knew what he signed up for."

Myeshia Johnson's comments in an ABC interview, her first to the media about the call from Trump, fueled a controversy that has raged for a week over how the president has handled consoling relatives of fallen service members.

After the interview aired, Trump again defended himself, saying in a Twitter post that his conversation with Johnson had been "very respectful."
