“First Eric CantorEric CantorTrump nominates two new DOD officials Brat: New ObamaCare repeal bill has 'significant' changes Overnight Energy: Flint lawmaker pushes EPA for new lead rule MORE, the Republican Whip, marches out of there with his teddy bear and Republican blanket,” Boxer said. “And then a few weeks later, BoehnerJohn BoehnerLobbyists bounce back under Trump Business groups silent on Trump's Ex-Im nominee Chaffetz won't run for reelection MORE walks out.”

Boxer likely was referring to an episode in the negotiations last month when Cantor, who is actually the House majority leader, abandoned the debt-ceiling negotiations out of frustration. Cantor was the whip when the GOP was the minority party in the House.

At the time of the walkout, Cantor reportedly said “it is up to the president to come in and talk to the Speaker [of the House John BoehnerJohn BoehnerLobbyists bounce back under Trump Business groups silent on Trump's Ex-Im nominee Chaffetz won't run for reelection MORE (R-Ohio)].

Boxer compared Cantor’s exit to what she described as House Minority Leader Nancy Pelosi’s (D-Calif.) long-suffering approach to negotiations with former President Bush.

“I watched Speaker Pelosi sit at the White House many times,” Boxer said. “She sat across from George W. Bush. She did not agree with him … but Nancy Pelosi never stomped out of a meeting.”

“I find it, frankly, appalling that thats what happened,” Boxer concluded.

Shortly after Boxers remarks the Senate adjourned and is set to return at 10 a.m. Thursday.
