Gen. Milley faces his toughest day yet on Capitol Hill

Gen. Mark Milley is expected to face a GOP grilling on Tuesday and Wednesday weeks after a number of Republicans said he should resign for threatening the principle of civilian control of the military.

Milley, the chairman of the joints chiefs of staff, was criticized for “treasonous” behavior by Sen. Marco Rubio (R-Fla.) and others after revelations in a new book, “Peril,” that Milley assured his Chinese counterpart that the U.S. was not about to launch a strike in the final days of the Trump administration.

Milley can also expect to take some bipartisan hits over the U.S. military’s withdrawal from Afghanistan and a drone strike that killed 10 people in the country and was later ruled a mistake. Milley had said it was a “righteous” strike.

“I think his credibility, and career, is on the line,” one former senior Defense official told The Hill. “I think he’s gonna get a grilling like he’s never seen before. And if he takes the bait and gets argumentative and defensive, it’s gonna be a big problem.”
