WASHINGTON  — He started by describing the reverent handling of America’s war dead, bodies packed in ice and shipped home in the dark to Dover Air Force Base.

From that opening, White House chief of staff John Kelly delivered a raw and searing monologue Thursday about the reality and pain of war sacrifice, praising those who serve and summoning the 2010 death of his own son to defend President Donald Trump against accusations of insensitive outreach to a grieving military family.

In an unannounced appearance at the White House, Kelly, a retired three-star general whose son was killed while serving in Afghanistan, dressed down the Democratic congresswoman who had criticized Trump for comments she said he had made in a condolence call to the pregnant widow of a Green Beret killed in Niger.

Kelly called Rep Frederica Wilson of Florida an “empty barrel” who “makes noise,” but he did not deny the lawmaker’s account of the phone call, as the president had this week. Throughout his remarks, Kelly lamented what he said was lost respect for military service, women, authority and more.

“I was stunned when I came to work yesterday morning, and brokenhearted at what I saw a member of Congress doing,” Kelly said. “Absolutely stuns me. And I thought at least that was sacred.”

The remarkable scene underscored Kelly’s singular role as an authoritative adviser and now spokesman for a president who is prone to false claims, exaggerations and misstatements. Kelly, who joined the White House to restore internal order, has increasingly become a public figure himself, employed to project calm and reassurance in times of crisis.

Kelly personally absolved Trump of blame in his call to the family of Sgt. La David Johnson, a conversation that prompted Wilson to declare that the president had been disrespectful to the grieving family and couldn’t remember Johnson’s name.

“If you’re not in the family, if you’ve never worn the uniform, if you’ve never been in combat, you can’t even imagine how to make that call,” Kelly said. “I think he very bravely does make those calls.”

Trump has emphatically rejected claims that he was disrespectful. But he started the latest controversy this week when he boasted about his commitment to calling service members’ next of kin and brought Kelly into the issue by wondering aloud if President Barack Obama had called the former Marine general after the death of Kelly’s son.

Kelly confirmed Thursday that Obama had not called him, but he made clear “that was not a criticism.”
