Democratic Rep. Jahana Hayes won reelection against Republican former state Sen. George Logan in a close rematch for the 5th Congressional District.
The Associated Press called the race just after 2 a.m.
In 2022, Logan lost by 2,000 voters.
Hayes secured her fourth term in Congress. She addressed her supporters earlier in the evening during her campaign party in Waterbury.
"Thank you for all of your faith in me and for continuing to trust me with your vote, which fundamentally is just your most precious right, and you are trusting me to be your voice for that vote. And it is not lost on me that responsibility," she said.
