Sen. Elissa Slotkin (D-Mich.) denounced Defense Secretary Pete Hegseth's lack of "guts and balls" during a hearing Tuesday when he refused to say whether he'd given orders to the military to shoot at unarmed protesters.

The heated exchange one of several during Hegseth's series of hearings before the Senate Armed Services Committee kicked off when Hegseth apparently laughed at Slotkin's inquiry about whether he'd given such orders.
