Myeshia Johnson broke her silence Monday morning, recalling how U.S. President Donald Trump struggled to remember the name of fallen Green Beret La David T Johnson who was recently killed during an ambush in Niger.

In an interview with "Good Morning America," Johnson spoke about the mounting controversy over the President's comments in which he told her that Johnson "knew what he signed up for."

Johnson confirmed previous reports that Trump failed to remember her husband's name, saying, "I heard him stumbling [over] trying to remember my husband's name, and that's what hurt me the most."

Trump immediately responded on Twitter to refute Johnson's claim, writing, "I had a very respectful conversation with the widow of Sgt. La David Johnson, and spoke his name from beginning, without hesitation!"

Johnson added that the military has told her little about what happened to her husband and his comrades in Niger, where about 800 U.S. troops are engaged in counter-terrorism operations against an affiliate of the Islamic State militant group.

She also said she was upset she has not been allowed to see his body. "I don't know what's in that box," said of the coffin. "It could be empty for all I know."

Johnson said she did not say anything during the call with the president, adding that afterward, she was "very upset and hurt. It made me cry even worse." Asked what she might now tell Trump, she said she had "nothing to say to him."
