As nasty as the battle over the fiscal crisis bill looked on the floors of Congress, it was even nastier behind the scenes.
The outburst came after Reid, on Thursday, took to the floor and likened Boehner to a dictator. Reid had claimed Boehner was holding back a bill out of concern for his speakership.
"John Boehner seems to care more about keeping his speakership than about keeping the nation on firm financial footing," Reid said Thursday, claiming the chamber was "being operated with a dictatorship of the speaker."
Boehner did not take kindly to the accusation. Politico first reported that Boehner swore at Reid when he saw him the next day at the White House, where congressional leaders were convening for a meeting.
Reid reportedly seemed startled, asking, "What are you talking about?" Boehner then repeated, "Go f--- yourself."
Boehner's office offered "no comment" on the incident.
