Summary

It's possible that the White House may be looking to replace Defense Secretary Pete Hegseth after critics warned that a pair of controversial Signal chats risked compromising US national security. On Monday, Trump defended Hegseth's Signal use, insisting that the defense secretary is "doing a great job," NBC News reported. Critics have urged Trump to take Hegseth's unauthorized Signal use seriously, warning that sharing confidential military information puts US operations and personnel at risk. On Sunday, former chief Pentagon spokesperson, John Ullyot, warned in a Politico op-ed that Hegseth's sloppy Signal use had caused "a near collapse inside the Pentagon’s top ranks." Perhaps hoping to appeal to Trump's ego, Ullyot warned that Hegseth's scandal has been a "major distraction" and declared that Trump—who "has a strong record of holding his top officials to account"—"deserves better."
