Three days after being sworn into Congress, Representative Peter Meijer, Republican of Michigan, was sitting in the gallery of the House of Representatives as pro-Trump rioters stormed the Capitol.

After the siege, Mr. Meijer made his feelings clear: President Trump’s actions proved that he was “rankly unfit.” A week later, he became one of just a handful of Republicans to vote for impeachment.

We talk with Mr. Meijer about his decision, his party and his ambitions.

Guest: Representative Peter Meijer, a first-term Republican congressman from Michigan.
