WASHINGTON, DC -- U.S. Senator Bob Casey (D - Pennsylvania) is changing his stance on gun control in light of last week's shooting in Connecticut.
       The Pennsylvania Democrat, has opposed new gun laws for a long time. He tells the Philadelphia Inquirer he's been haunted by the shootings that killed 27 people in Newtown.
       Casey says he now supports bills banning assault weapons and high-capacity ammunition clips, and he will vote for them if they come before the Senate.
