Earlier Thursday, Reid and Senate Minority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellGOP strategist donates to Alabama Democrat McConnell names Senate GOP tax conferees Brent Budowsky: A plea to Alabama voters MORE (R-Ky.) debated the potential use of the “nuclear option" — a parliamentary move to change the Senate rules by a simple majority vote — in order to thwart Republican efforts to block some of President Obama’s nominees.

Reid is expected to file cloture on several of Obama's controversial nominees later Thursday, setting up votes as early as next week.

At the beginning of the 113th Congress, Reid and McConnell agreed not to change the rules without a supermajority as long as Republicans didn’t block the administration’s nominees except in “extraordinary circumstances.”

Reid argued that Republicans have broken their agreement by blocking several nominees, while McConnell has accused Reid of trying to “break the rules to change the rules.”

“We really don’t need to go down this road,” Roberts said. “[Reid] believes he needs to destroy the United States Senate in order to save the United States Senate.”

Lawmakers met with other members of their party at caucus lunches Thursday to discuss how to proceed on rule changes. Roberts, the ranking member of the Senate Rules Committee, said any rule changes should be done through regular order in committee.

Roberts quoted Vice President Biden opposing the "nuclear option" when he was a senator. His phone then began ringing on the floor. Roberts joked that Biden was calling him.
