President Trump’s defense secretary, Pete Hegseth, is imploding again. We just learned that he shared still more highly sensitive data on a private Signal chat. A GOP congressman just basically called for his resignation. And a former chief Pentagon official who is a Trump supporter himself also tore into Hegseth’s tenure, calling it a “full-blown meltdown.” That triggered a furious response from Donald Trump Jr., who declared this turncoat critic “exiled” from the Trump movement. Other MAGA figures raged at Hegseth’s critics as well. We talked to Juliette Kayyem, a former national security official under Barack Obama. She takes us through this latest scandal and explains why the profoundly unfit Hegseth will become a much, much bigger problem for Trump—with no easy way out for the president.
