Both campaigns responded to the Colorado shooting by pulling their ads in the state which could mean a week of toned-down campaigning. But then again, it might not.

The Libor rigging scandal that started at Barclay's in London has landed, in its most recent episode, at the Federal Reserve Bank of New York. Reports that Barclay's met with the New York Fed about Libor in 2007 and 2008 implicate then-president Timothy Geithner.

White House officials are already criticizing journalist Ron Suskind's book "Confidence Men: Wall Street, Washington, and the Education of a President," which just came out this week, despite having cooperated with Suskind for years. Among the book's more controversial passages are depictions of the Obama White House as dysfunctional, with mean, misogynistic economic advisers undermining a clueless president at every turn. Treasury Secretary Timothy Geithner said, "I lived the original and the reality I lived, we all lived together, bears no relation to the sad little stories I heard reported from that book." White House Press Secretary Jay Carney went even further and accused Suskind of plagiarism, saying, "one passage seems to be lifted almost entirely from Wikipedia."
