Sen. Orrin Hatch, R-Utah, riled up protesters Thursday on Capitol Hill when he suggested a group demonstrating against Supreme Court nominee Brett Kavanaugh needed to "grow up."

Hatch waved off the activists when one woman asked why he wasn't "brave enough to talk to us and exchange with us" while he waited for an elevator.

"When you grow up, I’ll be ready," Hatch, who sits on the Senate Judiciary Committee, told the woman after she chastised him for using a hand gesture to shoo them away.

Hatch's response drew more ire from the group, with the same woman hurling an expletive at the Utah Republican. Another protester told him to take his own advice and dressed him down for speaking to women in a haughty manner.

The tense interaction was one of many on Thursday between senators and protesters hoping to sway lawmakers' votes to either support or oppose the judge's nomination for the highest court when it is considered on the Senate floor on Saturday.

Among those targeted by demonstrators was Hatch's Senate Judiciary colleague, Sen. Lindsey Graham, R-S.C. Both Hatch and Graham have indicated they will vote in favor of Kavanaugh's confirmation.
