In a speech on the Senate floor, Booker praised the success of their bipartisan effort to extend an assisted living program for veterans with traumatic brain injuries.

“I only wish he had shaved his head as I have,” Booker said to Heller. “That would have shown true bipartisan camaraderie.”

Booker sports a shaved head, while Heller has a full head of hair. Heller only acknowledged the comment with a chuckle.

Their legislative language was included in a bill designed to overhaul the Department of Veterans Affairs healthcare system.

The House passed that bipartisan conference report on Wednesday, and the Senate is expected to act later Thursday.
