Hegseth: 'Resist' Movement Will Twist Trump's Words Even About a Dead Soldier

Newt Gingrich said the controversy over President Donald Trump's call to a Gold Star widow shows how "deranged" the left has become.

Rep. Frederica Wilson (D-Fla.) claimed Tuesday that Trump told the widow of Army Sgt. La David Johnson during a phone call that "he knew what he signed up for." Johnson was among four service members killed earlier this month during an ambush in Niger.

"Unfortunately there are some politicians and some reporters who have lost their way," Gingrich said on "America's Newsroom." "This is tragic for America that we're going to turn commiseration to a Gold Star wife into a political football."

He said White House Chief of Staff John Kelly's comments on the controversy - in which he said he was "stunned" that a member of Congress would politicize a fallen soldier - were remarkably powerful and emotional.

Wilson responded to Kelly's remarks on Friday by accusing him of lying about her and using a "racist term" directed at her.

"It tells you the level of hatred on the left that's left them, frankly, a little bit deranged and unable to show any decency in situations like this," Gingrich said.

"I think you saw a very simple contrast - a man who has served his country for over 40 years, risked his life, lost his son, dedicated himself to defending America and, frankly, a politician who doesn't know anything, has no shame, has no sense of understanding and can't figure out the time has come to keep her mouth shut."
