Collin Peterson will end his career as one of Minnesota’s longest-serving members of Congress, having spent 30 years in Washington, D.C. In that time, he developed a reputation for bipartisanship and independence.

He is one of the last rural Democrats in Congress, and frequently bucked his party on issues such as the environment and creating the Affordable Care Act. When he breaks with his party, he says he is merely reflecting the views of his district. Peterson was one of only two Democrats to vote against the impeachment of President Donald Trump. He opposes abortion and is the lone Democrat in Congress with an A-rating from the NRA. Peterson is the first Minnesotan to serve as chairman of the powerful House Agriculture Committee, highlighting his deep understanding of rural issues and international agricultural policy.

Peterson's seat was a loss for congressional Democrats who hoped a "blue wave" would help expand their vote margin in the U.S. House of Representatives in 2020 – an expectation that didn't materialize.

Peterson often flies a single-engine airplane to get around his district, which stretches roughly 35,000 square miles across much of the western border of the state.

Country music star Willie Nelson invites Peterson to play at Farm Aid to lend political heft to the fundraiser. Peterson played in several bands in Washington, including a cover band called the Second Amendments.

"He told me I could play as long as I wanted, but I know how that goes," Peterson said at the time. "He's kind of like a member of Congress telling a constituent what they want to hear.”

Feb. 7, 2019

Peterson again serves as chairman of the House Agriculture Committee.

“We’ve got a lot of work to do,” Peterson said during the organizational meeting. “We have a great opportunity to drive real, tangible and bipartisan progress for Americansin all communities, rural or urban, from this Committee. Now it won’t be flashy—as far as I know, nobody’s ever accused me of that—but it will be important work.”

Dec. 2019

Peterson tells the Star Tribune that prominent Republicans in Washington have urged him to switch parties but he has no intention of doing so. Peterson is a conservative Democrat, he’s anti-abortion, supports mining and bucks the party on the Affordable Care Act.

Dec. 18, 2019

In a break with his party, Peterson opposes two articles of impeachment against President Donald Trump. He’s one of two Democrats to oppose the measures. The other, Rep. Jeff Van Drew of New Jersey, is now a Republican.

“I don’t condone what the president did,” Peterson said. “But at the beginning of this thing they said they were going to have bipartisan support or not move ahead. There’s no bipartisan support. It’s just going to further divide the country.”

Nov. 3, 2020

Peterson loses his reelection battle to Republican Michelle Fischbach, a former lieutenant governor and state senator. He had served in the House for 15 consecutive terms.

"I'd like to thank the people of the Seventh District for their support over the years,” Peterson said in a press release. “Serving them in Washington DC has been a great honor, and I respect their decision to move in a different direction. We ran a strong and positive campaign, but with the President winning this district by 30 points again, and the millions in outside money that was spent to attack me, the partisan tilt of this district was just too much to overcome."

He has not granted interviews about the election since his defeat.
