What’s Landrieu Got to Hide?

Sen. Mary Landrieu’s campaign turned over $25,300 in campaign contributions to the U.S. Treasury last year, a move that appears to have been intended to disgorge contributions that were legally questionable. But at the same time the campaign calls the move “routine” — a description one campaign finance expert calls “bullshit” — and refuses to provide any details about who the contributor was or why the campaign coughed up the money. CREW is now filing an FEC complaint. What gives?
