WASHINGTON — President Trump on Saturday jabbed back at the Democratic lawmaker who slammed him for his words of condolence to a military widow, calling Rep. Frederica Wilson “wacky” and contending she is “killing” her party.

Trump’s broadside came a day after the White House defended chief of staff John Kelly after he mischaracterized Wilson’s remarks and called her an “empty barrel” making noise. A Trump spokeswoman said it was “inappropriate” to question Kelly in light of his stature as a retired four-star general.

The fight between Trump and the Miami-area Democrat began Tuesday when she said Trump told the pregnant widow of a service member killed in the African nation of Niger that her 25-year-old husband “knew what he signed up for.” Wilson was riding with the family of Sgt. La David Johnson to meet the body and heard the call on speakerphone.

The administration has tried to insist that it’s long past time to end the political squabbling over Trump’s compassion for America’s war dead.

But Trump added to the volley of insults with his tweet Saturday morning: “I hope the Fake News Media keeps talking about Wacky Congresswoman Wilson in that she, as a representative, is killing the Democrat Party!” That came after she had added a new element by suggesting a racial context.

His tweet came hours before mourners were to attend Johnson’s funeral in a suburb of Fort Lauderdale, Florida.

Kelly asserted that the congresswoman had delivered a 2015 speech at an FBI field office dedication in which she “talked about how she was instrumental in getting the funding for that building,” rather than keeping the focus on the fallen agents for which it was named. Video of the speech contradicted his recollection.

Wilson, in an interview Friday with The New York Times, brought race into the dispute.

“The White House itself is full of white supremacists,” said Wilson, who is black, as is the Florida family Trump had called in a condolence effort this week that led to the back-and-forth name-calling.

Trump, in an interview with Fox Business Network, then called Wilson’s criticism of Kelly “sickening.” He also said he had a “very nice call,” with the late sergeant’s family.

The spat started when Wilson told reporters that Trump had insulted the family of Johnson, who was killed two weeks ago in Niger. She was fabricating that, Trump said. The soldier’s widow and aunt said no, it was the president who was fibbing.

Then Kelly strode out in the White House briefing room on Thursday, backing up the president and suggesting Wilson was just grandstanding – as he said she had at the FBI dedication in 2015.

After news accounts took issue with part of that last accusation, White House press secretary Sarah Huckabee Sanders chastised reporters for questioning the account of a decorated general.
