Democratic critics along with some Republicans are calling for Mitt Romney to disclose more than two years of tax returns in the lead up to the November presidential election.
While some are wondering whether the former Bain Capital executive might be hiding offshore accounts, Romney supporters are saying their candidate has nothing to hide.
Romney supporter Sen. Ron Johnson (R-WI) tells Soledad O'Brien on CNN's "Starting Point" that American voters are not concerned about Romney's tax returns or his history at Bain.
"I never hear it," Sen. Johnson says. "When I'm back in Wisconsin, when I travel around America, nobody ever talks to me about those issues. They're talking to me about what we can do to get unemployment below the 8 percent..."
Sen. Johnson adds, "At some point in time you just draw the line and say, listen, the American people have enough information. And I think they do."
