MIAMI - With a week to go until Election Day, more nasty campaign tactics are coming out.
People in Florida, Virginia and Indiana have gotten calls falsely telling them they can vote early by phone and don't need to go to a polling place.
Indiana's secretary of state launched an investigation. Virginia officials issued a warning to voters and asked them to report any such calls they receive.
And there's a mysterious DVD popping up in mailboxes that purports to be a "documentary" raising questions about the true identity of President Barack Obama's father.
Letters have also been sent to Republicans questioning their citizenship and right to vote. The FBI is investigating the letters, which were postmarked in Seattle.
