President Trump has deployed National Guard troops to Portland, Chicago and D.C., and while Democrat-led states are fighting back, some Republican-led states are welcoming the troops -- even requesting them. Tonya Mosley talks with Atlantic national security staff writer Nancy Youssef about these deployments and the tensions building inside the Pentagon. Defense Secretary Hegseth has told military leaders the “old military is over." "The decisions that are being made now will reshape the military for many years," Youssef says.
