"In recent weeks, it's become absolutely clear that this committee is nothing more than a political hit job on Hillary Clinton," the Democratic leader said. "They're going to bring her in tomorrow. They said be ready for eight hours, eight hours of interrogation, and that's what this is, interrogation." 
Reid added that Senate Democrats have sent a letter to the Republican National Committee (RNC) asking that it reimburse the American taxpayers for any money spent on the Benghazi committee. 
Reid said the request is "only fair since the so-called committee is clearly a Republican political organization."
Clinton will testify Thursday before the House committee, which is tasked with investigating the Sept. 11, 2012, attack in Benghazi, Libya, that left four Americans dead. 
The House committee has been under attack from Democrats, including Reid, in recent weeks after House Majority Leader Kevin McCarthy (R-Calif.) linked the committee's work to Clinton's trouble in the polls. 
Reid said Wednesday that the comments were "one reason" McCarthy withdrew from the race to succeed outgoing Speaker John BoehnerJohn Andrew BoehnerLobbying world A new kind of hero?

"The notion that an official House committee was used as a political tool is inexplicable," he added. "I would suggest the chairman of that committee should be ashamed of himself."
