Congressional watchdog group Common Cause is raising a red flag against money in politics with a series of protests starting Thursday.

In light of the BP oil spill, the group, along with Public Campaign, is planning to protest outside a Capitol Hill fundraiser for Rep. Gregg Harper (R-Miss.), according to Common Cause spokeswoman Mary Boyle.

“Even when there’s a crisis, a Member can’t drop everything in Washington,” Boyle said. “The idea is to highlight how much time Members of Congress and all of Washington spends to feed this campaign finance system.”

Harper’s spokesman did not immediately respond with a comment. His district is not part of the Gulf Coast region that has been hit by the oil spill.

Still, Boyle said the group will hold signs and plans to videotape people going into the fundraiser and hopes to ask Harper whether he thinks he should be back in his state dealing with the crisis instead of fundraising in D.C.

Common Cause is advocating for Congress to address campaign finance reform. The group is pushing for public financing for Congressional campaigns, and it plans to stage similar demonstrations at other Members’ events.
