On Monday, even as White House officials conceded privately that they had to find a way to move beyond the episode, Mr. Trump refused to back down, posting a message on Twitter that contradicted Ms. Johnsonâs account after her interview was broadcast.
The presidentâs response seemed certain to keep alive the extraordinary squabble, which erupted a week ago when Mr. Trump was asked about the deadly ambush in Niger and asserted wrongly that previous presidents had not called the families of American troops killed in action. He then proceeded to call relatives of the soldiers killed in Niger, only to have Representative Frederica S. Wilson, a Florida Democrat who listened to Mr. Trumpâs conversation with Ms. Johnson, criticize the president publicly for his words.
On Monday, Ms. Johnson supported Ms. Wilson, who has been feuding with both Mr. Trump and Mr. Kelly over the call.
âWhatever Ms. Wilson said was not fabricated,â Ms. Johnson said. âWhat she said was 100 percent correct.â
Ms. Johnson said that on the call, she let Mr. Trump do most of the talking as her anger grew. When asked if she wanted to say anything to Mr. Trump, the young widow decided against delivering a message.
She did, however, say that she was desperate to know more details about the disappearance and death of her husband, and described him as âcaringâ and a âgreat soldier.â The couple had known each other since she was 6 years old.
âI want to know why it took them 48 hours to find my husband,â Ms. Johnson said.
She also shared a deep concern over not being allowed to view her husbandâs remains.
âThey wonât show me a finger, a hand,â she said. âI know my husbandâs body from head to toe and they wonât let me see anything,â she said. âI need to see my husband.â
After a service member is killed on the battlefield, the militaryâs mortuary affairs personnel often do everything they can to prepare the deceased for a potential viewing. In some cases, however, if the wounds are too grievous or the body is extremely disfigured, the military might suggest that the coffin remain sealed.
Tech. Sgt. Holly Roberts-Davis, who is in charge of public affairs at Dover Air Force Baseâs mortuary affairs division, said that families were not allowed to see the remains of their loved ones until after the body is inspected and cleared by the divisionâs medical examiner. Once that is complete, the family is free to open the coffin.
The back and forth began after Sergeant Johnson and three Americans were killed in an Oct. 4 ambush in Niger. The president called Ms. Johnson and said that her husband âknew what he signed up for,â and referred to the soldier as âyour guy.â Ms. Wilson, a longtime family friend who accompanied Ms. Johnson and heard the call, recounted what the president said to several reporters and lamented that the president had offended the young widow, who was upset that the president did not seem to know Sergeant Johnsonâs name.
Mr. Trump angrily disputed that account, saying that he âhad a very nice conversation with the woman, with the wife, who sounded like a lovely woman.â
Last week, Mr. Trump said on Twitter that Ms. Wilsonâs account was âtotally fabricated,â although the woman who raised Sergeant Johnson said it was accurate. And Mr. Trump has continued to target the congresswoman, calling her âwacky.â
In a White House briefing, Mr. Kelly harshly criticized Ms. Wilson, who had known Sergeant Johnsonâs family since he was in elementary school, for listening to the call. Mr. Kelly called the lawmaker an âempty barrelâ and also misrepresented her remarks when he accused her of bragging about securing $20 million for an F.B.I. building in South Florida and twisting President Barack Obamaâs arm.
Video of Ms. Wilsonâs speech, released by The Sun Sentinel, a newspaper in South Florida, showed that during her nine-minute speech, Ms. Wilson never took credit for getting the money for the building, only for helping pass legislation to name the building after two fallen federal agents. She also never mentioned pleading with Mr. Obama, and she acknowledged the help of several Republicans, including John A. Boehner, then the House speaker; Representatives Mario Diaz-Balart and Carlos Curbelo; and Senator Marco Rubio.
On Monday, Ms. Johnson also pushed back against Mr. Kellyâs criticism of Ms. Wilson for hearing the call. The widow said she had asked the military official accompanying her family to put the call from President Trump on speakerphone so others could also hear his words.
Sarah Huckabee Sanders, the White House press secretary, said that Mr. Kelly âabsolutelyâ stands by his Thursday remarks.
âGeneral Kelly said he was âstunnedâ that Representative Wilson made comments at a building dedication honoring slain F.B.I. agents about her own actions in Congress, including lobbying former President Obama on legislation,â Ms. Sanders said in a statement. âAs General Kelly pointed out, if youâre able to make a sacred act like honoring American heroes about yourself, youâre an empty barrel.â
Over the weekend, the dispute continued with Mr. Trump posting Sunday on Twitter, âWacky Congresswoman Wilson is the gift that keeps on giving for the Republican Party, a disaster for Dems. You watch her in action & vote R!â
Several women from the Congressional Black Caucus also wrote a letter demanding an apology from Mr. Kelly.
âWe were appalled by White House Chief of Staff John Kellyâs statements where he called Congresswoman Wilson an âempty barrelâ and accused her of taking credit for securing funding for a new F.B.I. Building,â the lawmakers said.
âGeneral Kellyâs comments are reprehensible,â the letter stated. âCongresswoman Wilsonâs integrity and credibility should not be challenged or undermined by such blatant lies. We, the women of the Congressional Black Caucus, proudly stand with Congresswoman Wilson and demand that General Kelly apologize to her without delay and take responsibility for his reckless and false statements.â
