Washington (CNN) Republican Sen. Steve Daines of Montana will be out Saturday because he will be walking his daughter down the aisle at her wedding, and would miss a confirmation vote for Supreme Court nominee Brett Kavanaugh held that day.

The Senate is currently on track to take a key procedural vote to advance the nomination on Friday morning, with a final confirmation vote possible at about 5 p.m Saturday.

Daines told CNN on Thursday that GOP leaders may be forced to hold open the confirmation vote for Kavanaugh overnight as the senator returns to Washington from his home state, where his daughter is being married.

"I'd come back after the wedding," he told CNN.

"It will probably be early morning," Daines said, suggesting he wouldn't get back until sometime early Sunday. "We're taking it a day at a time to see what happens."
