La David Johnson, one of four USA soldiers killed in Niger, took place on Saturday, his tragic death politicized by the president, who continues to feud with a Congresswoman who was close to the family.
Mr Trump has rejected the claims, tweeting that the pair had "a very respectful conversation" and he used Sgt Johnson's name "from beginning, without hesitation!"
He also said that it "stuns me that a member of Congress would have listened in on that conversation".

Trump tweeted Wilson "fabricated" his statement and the fight escalated through the week.
The military unit ambushed in Africa earlier this month didn't call for support until an hour after the attack and French jets didn't reach the scene for another hour, the chairman of the Joint Chiefs of Staff said on Monday.
Last week, Trump called the Gold Star widow while she was in a auto, and she asked that the conversation be put on a speaker phone.
"It made me cry because I was very angry about the tone of his voice and how he said it", Johnson said.
Myeshia Johnson told "Good Morning America". Wilson was riding with Johnson's family to meet the body and heard the call on speakerphone.
Johnson, 25, was one of four U.S. Special Forces - or Green Berets - killed in Niger when they were attacked October 4 by militants tied to the Islamic State.
'And to be extremely candid, as a black man, I am always looking for role models who look like me, and the latest one I found was your husband. "Every time I asked to see my husband, they wouldn't let me".
"They won't show me a finger, a hand".
Johnson's GMA appearance comes during a swirling political debate over the circumstances of the death of her husband and three other U.S. soldiers in Niger. I don't know what's in that box.
"Whatever Mrs. Wilson said was not fabricated". She stated she has nothing to say to Trump now. "I heard him stumbling on trying to remember my husband's name, and that hurt me the most because if my husband is out here fighting for our country and he risks his life for our country, why can't you remember his name?" "A couple of days later is when they told me he went from missing to killed in action".
