U.S. Senate candidate John Fetterman is attacking opponent Mehmet Oz’s connections to Pennsylvania. Over the weekend, the Democrat’s campaign started airing an ad questioning the celebrity doctor’s residency in the commonwealth. Fetterman’s ad claims his Republican opponent only moved to the state to run for the seat of retiring GOP Senator Pat Toomey. It also says Dr. Oz moved in with his mother-in-law to qualify to run.
