Rep. Rick Nolan, D-Minn., announced Friday that he will not run for re-election in November, and will retire.

"The fact is, I have spent 16 productive and exciting years in elective office, and far longer working behind the scenes in business, labor, community service, and the public policy arena," Nolan said in a statement. "Good politics is about making a positive difference in people’s lives, and together with all of you and a brilliant dedicated staff, we’ve made a real difference for the 8th District of Minnesota and our great Nation."

"Having said that, there is a time and a purpose for everything and now is the time for me to pass the baton to the next generation," he added.

Nolan is in one of the few true toss-up districts that are currently held by Democrats. In 2016, Nolan won by less than one percentage point while President Trump carried his district by nearly 16 points. He is one of two Minnesota lawmakers vacating their seat ahead of 2018 — the other, Rep. Tim Walz, D-Minn., is running for governor in the fall.

The Minnesota lawmaker is in the middle of his third consecutive term in the House, and also served from 1975 to 1981.

Despite the Republican bent in his district, Democrats are confident they will hold onto the seat in November as they look to retake the House majority for the first time since 2010.

“Minnesota’s Eighth Congressional District is a Democratic seat, and that certainly will not change in 2018," said Rep. Ben Ray Lujan, D-Minn., chairman of the Democratic Congressional Campaign Committee (DCCC) in a statement. "We look forward to electing another Democrat to represent the hardworking people of northern Minnesota, who can carry on Rick’s legacy."
