Mitt Romney knows more about Paul Ryan's taxes than America will.

Ryan told 60 Minutes Sunday that he gave Romney's campaign "several" years of tax returns during the vetting process, but promised only to release two publicly, in keeping with the number Romney has promised to release. 

He dismissed calls from both Democrats and Republicans for Romney to release more of his tax returns.

"I think these issues are more or less distractions to try and take us off the fact that the president has given us failed policies that are putting us deeper into debt, that are costing us jobs," Ryan said. 

The 42 year-old congressman said he went through a "very exhaustive vetting process" before being selected as Romney's running mate. He said the process was "confidential."
