Republican U.S. Sen. Ron Johnson of Wisconsin, one of former President Donald Trump’s most vocal supporters, says he will seek reelection to a third term.

Republican U.S. Sen. Ron Johnson of Wisconsin, one of former President Donald Trump’s most vocal supporters, has decided to seek reelection to a third term.

Priebus would only consider running for Senate if incumbent Republican Ron Johnson did not seek a third term, the strategist said. Some began reaching out to Priebus after conservative talk radio host Jay Weber floated Priebus' name, the strategist said. Priebus served as Trump's chief of staff for the first six months of Trump's term in 2017 before being fired. Priebus last voted in Wisconsin in the 2016 presidential election, when Trump narrowly won the state. AdPriebus, a native of Kenosha, was head of the Wisconsin Republican Party between 2007 and 2009 before spending the next six years as chairman of the Republican National Committee.

Biden inched past Trump on Friday and led by about 11,600 votes on Monday afternoon, though the AP has not called the race. The AP has called Nevada for Biden, who was leading Trump by about 36,000 votes. The reality: Biden defeated Trump by about 20,500 votes in Wisconsin, a margin of about six-tenths of a point. The initial margins in those races were 137 votes, 215 votes and 261 votes.

The two men stood side by side on the House floor as they were sworn into office by Speaker Nancy Pelosi, D-Calif. Rep. Tom Emmer, R-Minn., who leads the House GOP's campaign arm, has said it means his party can win the House. But Democrats are still favored to retain House control and seem likely to keep most contested suburban seats this November. He replaces former GOP Rep. Sean Duffy, who said he left office to spend more time with his family. With Garcia and Tiffany joining the House, Democrats control the chamber 233-198, with one independent and three vacancies.
