It’s all setting up a major confrontation next week if the Justice Department doesn’t send the full Mueller report to Congress by Tuesday, as six committee chairmen have demanded.

The next step, the staffers said, would be a subpoena. “We’ll have more to say on April 3,” one staffer said.

Democrats are also fleshing out the legal and political arguments they’ll make next week if the Justice Department does refuse to release the report.

They’ll insist there’s no reason the president could not be charged with obstructing the investigation — making the point that Deputy Attorney General Rod Rosenstein repeatedly charged defendants with obstruction even if he didn’t charge them with an underlying crime.
