Presumed Republican presidential nominee Mitt Romney released his 2010 tax returns, and an estimate of his taxes for last year.

But, so far, he's refused to share returns from previous years.

Some Democrats, like House Minority Leader Nancy Pelosi and Senate Majority Leader Harry Reid, claim that's only because he has something to hide.

But, as members of the Congressional leadership, neither of them have made their tax returns public.

That's the subject of a report co-written by Kevin Hall of the McClatchy Newspapers, who joins the show.
