Pence makes history, enters 2024 Republican race running against his former boss Donald Trump

Former Vice President Mike Pence spotlighted his differences with his two-time running mate — former President Donald Trump — as he formally declared his candidacy for president on Wednesday at a campaign launch event in Iowa, the state that leads off the Republican presidential nominating calendar.

Pence joins a growing field of Republican White House contenders that’s currently dominated by Trump. And he's making history as the first running mate in eight decades to run against his former boss, since Vice President John Nance Garner unsuccessfully challenged President Franklin Roosevelt in the 1940 election.

"As your vice president, I stood by president Donald Trump every single day when we made America great," Pence said to a crowd of friends, supporters, and Iowa voters interested to hear what he had to say, who were gathered at Des Moines Area Community College.

But the former vice president, who touts the Trump-Pence administration’s policy successes but contrasts himself with the controversial former president in terms of tone and tenor, said that "elections are about the future. Different times call or different leaders."
