The notification from the Judiciary Committee didn’t specify when, or if, the committee votes on the nominations would be rescheduled. Six circuit court nominees had been expected to get a vote, as well as 15 district court nominees.

But Grassley warned late Wednesday afternoon that he would likely cancel the meeting unless he could get a deal with Flake that would allow the nominations to move forward.

“We haven’t canceled the meeting yet,” Grassley said roughly an hour before the announcement. “If we don’t get a positive out of it, we’ll probably cancel the meeting.”

Republicans hold a 51-49 majority in the Senate, allowing them to move Trump's nominees despite Flake as long as the remaining 50 Republican senators remain united.

But on the Judiciary Committee Republicans are limited to a 11-10 majority, meaning they need Flake's support unless they can get help from Democrats.

The resolution, which cleared the Judiciary Committee earlier this year, would protect Mueller, or any other special counsel, in the event he is fired, but the bill has stalled amid opposition from GOP leadership.

The bill would codify Justice Department regulations that say only a senior department official could fire Mueller or another special counsel.

It would give a special counsel an "expedited review" of their firing. If a court determines that it wasn't for "good cause," the special counsel would be reinstated.
