AUSTIN, Texas — U.S. Senator Cory Booker was in Austin on Saturday, days after he faced backlash for releasing confidential judicial documents on Supreme Court Nominee Brett Kavanaugh.

Booker delivered the keynote address at the Texas Democrats' annual Johnson-Jordan Dinner.

His speech comes days after a heated exchange with U.S. Senator John Cornyn during Kavanaugh's confirmation hearing. Booker announced at the hearing that he would release documents made off limits by Republican members of the Senate Judiciary Committee. Cornyn shot back by saying the move could lead to a potential expulsion from the Senate.

"I invite him to follow through," Booker said. "Either he's a bully making a lot of idle threats or he's not."

Senators would need a two-thirds majority to expel Booker from the senate and Republicans are already laying the groundwork for a potential ethics investigation. Booker said he's standing by his actions to bring relevant information to the American people.

"America has the right to know the fullness of this person's resume and right now that's not happening," Booker said.

There's still no official date set for when the Judiciary Committee will vote on Kavanaugh's confirmation.
