“First Eric CantorEric CantorWhat to watch for in Comey’s testimony Trump nominates two new DOD officials Brat: New ObamaCare repeal bill has 'significant' changes MORE, the Republican Whip, marches out of there with his teddy bear and Republican blanket,” Boxer said. “And then a few weeks later, BoehnerJohn BoehnerRyan reminds lawmakers to be on time for votes Juan Williams: GOP fumbles on healthcare The Hill's 12:30 Report 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 BoehnerRyan reminds lawmakers to be on time for votes Juan Williams: GOP fumbles on healthcare The Hill's 12:30 Report 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.
