Mike Pence, former vice president of the United States, is now running for president.

He announced his candidacy on Wednesday, June 7, setting up a battle with his former boss, Donald Trump, for the Republican nomination.

When Trump made him his running mate, Pence was governor of Indiana. Before that, he served in the US House of Representatives from 2001 to 2013.

By 2009, Pence had risen to become the House Republican Conference chairman, a position he occupied as a leader of the party's socially conservative flank. During the 2010 Value Voter Summit, Pence took the stage and said, "I'm a Christian, a conservative and a Republican, in that order."

Pence holds a news conference in Indianapolis in March 2015. Pence spoke about the state's Religious Freedom Restoration Act, which banned local governments from intervening when businesses turn away customers for religious reasons. The law sparked concern about discrimination, particularly within the LGBT community. A week after it was enacted, Pence signed a new version that prohibited discrimination on the basis of sexual orientation.

Pence chose not to wear a face mask during the tour despite the facility's policy. Pence initially told reporters that he wasn't wearing a mask because he's often tested for coronavirus. He later said he should have worn one.
