MADISON, Wis., (AP) — Republican U.S. Sen. Ron Johnson, of Wisconsin, says half the country will not accept the outcome of the presidential election with Democrat Joe Biden’s win. Johnson also refused to say if he thought the election was legitimate, while admitting he had no proof of any illegal activity. Johnson says it is a “real problem” that voters won’t accept the outcome of the election. He says the large number of mail-in ballots increased the chances of wrongdoing. Wisconsin elections officials have said they have no evidence of any widespread problems.
