President Donald Trump’s nominee for chairman of the Joint Chiefs of Staff, Lt. Gen. Dan “Razin” Caine, will head to Capitol Hill Tuesday morning to testify at his confirmation hearing at 9:30 a.m. He will appear before the Senate Armed Services Committee.

Trump fired Caine’s predecessor, Gen. Charles Q. Brown Jr., in February. After the firing, he said Brown “has served with distinction in a career spanning four decades of honorable service,” and added, “I have come to know him as a thoughtful adviser and salute him for his distinguished service to our country.”
