The Democrat represents North Carolina's 7th Congressional district.
McIntyre, who is in his ninth term, released a statement Wednesday on his decision to retire after 18 years in the House of Representatives.
"This partnership has transcended politics and allowed us to accomplish monumental tasks, such as quadrupling the number of veterans' clinics in our area, passing the tobacco buyout, expanding our military bases, establishing an economic commission to promote jobs and fight poverty -- and ensuring that the North Carolina coast will continue to be an economic engine and environmental treasure," his statement said in part.
"We also have built new fire and police stations, town halls, and workforce development centers; opened new farmers' markets and senior centers; improved airports and the Wilmington Port; and expanded educational and recreational opportunities for our children and youth," McIntyre added. "We have helped thousands of constituents from all walks of life in ways that have significantly impacted their lives."
The Congressman said none of it "could have been accomplished without the strong commitment of my family, the hard work of my staff, and -- especially -- the willingness of people throughout our region to put partisanship aside and work together to get things done for the betterment of eastern North Carolina."
McIntyre told ABC11 that he will leave Washington without any regret.
"There's always challenges and always things that may have come out different than you thought, but we're very pleased with how well things went and how the record that we were able to accomplish and the difference that it's made in so many people's lives," said McIntyre.
North Carolina's 7th Congressional District encompasses a largely rural stretch of eastern North Carolina, which includes parts of Bladen, Brunswick, Columbus, Cumberland, Duplin, New Hanover, Pender, Robeson, and Sampson counties.
