White House chief of staff John Kelly lashed out at Rep. Frederica Wilson(D-Fla.) on Thursday, saying he was “stunned” by her negative description of President Trump’s call to the wife of a U.S. soldier killed in Niger.

“I was stunned when I came to work yesterday morning,” he told reporters during an impromptu appearance at the White House press briefing, adding he was “broken hearted” over the negative publicity surrounding the call.

Wilson revealed that Trump told the widow of Army Sgt. La David Johnson her husband “knew what he was getting into.”

“I would have thought that was sacred,” Kelly said of Trump’s conversation with Myeshia Johnson. Wilson was present for the call.
