Republican Representative Andy Barr of Kentucky has won a close-fought race that Democrats had targeted in a bid to shift the House to Democratic control.
Barr turned back a strong challenge from Democrat Amy McGrath in a district that supported President Donald Trump two years ago.
McGrath, a retired fighter pilot, gave Barr his toughest test yet as he sought a fourth term.
Barr urged voters to re-elect him for his "access and influence with this administration," while McGrath countered with a message of "country over party."
Barr won by 22 points in 2016, but McGrath waged an aggressive challenge, including TV ads showing her in front of fighter jets and with her young children.
