U.S. Senator Chuck Grassley is backing down a bit from a comment on Twitter in which he called President Obama "stupid." In a conference call with reporters, the Iowa Republican admitted he made a bit of a mistake. Grassley went on to again call Obama's remark "stupid" regarding the President's belief that the U.S. Supreme Court will uphold the Affordable Care Act. The senator was taking issue with remarks Obama said recently that the high court wouldn't overturn the law as being unconstitutional because it was passed by a majority in Congress.
