A Republican hoping to represent Michigan in the U.S. Senate suffered a setback to his campaign this week after facing allegations that he lives in Florida.

Former Congressman Mike Rogers, who has made much of his local roots in a bid to win over voters, faced backlash online after the staff of Democrat rival Elissa Slotkin released information on X, formerly Twitter, apparently proving he is still registered to vote in the Sunshine State.

The Republican Party hopes to retake the Senate on November 5 from the Democrats, who currently hold a slim majority. But polls released last month suggest that Democrats are leading the races in several states, including Michigan. One Emerson College Polling/The Hill survey of 1,000 voters found that 41 percent said they supported Slotkin while 39 percent said they would vote for Rogers.
