The four key centrist votes on Judge Brett Kavanaugh — Sens. Susan Collins, Lisa Murkowski, Jeff Flake and Joe Manchin — are huddled privately in a Capitol office.

Staff left the room as they gathered minutes after the Kavanaugh hearing ended.

Murkowski angrily tried to order a reporter from the hallway when she arrived.

“Go,” she shouted out pointing to the end of the hallway.

The three Republicans are planning to attend the GOP conference meeting at 7:15 p.m., per an aide.
