Republican incumbent Rep. Steve Knight has conceded to Democratic challenger Katie Hill.

Hill, who identifies as bisexual, will join Sharice Davids, from Kansas, and Angie Craig, from Minnesota, in representing LGBTQ women in the U.S. House. She is also one of the youngest women ever elected to Congress. Hill, 31, served as the executive director of PATH, a group that fights homelessness, and is a lifelong resident of the 25th District, which she will now represent.

Knight, an Army veteran and former police officer, was first elected in 2014, and was hurt by his tendency to vote with President Trump, who is unpopular throughout the state.

While votes were still being counted, and the race had not yet officially been decided, he called his opponent to admit defeat.

“The voters have spoken, and they want a new congressman—or a congresswoman, for this district,” Knight told the local CBS affiliate. “We wish her the best.”

"I'm very excited to get there and start working," Hill said. "The commitment and the focus has to be on, what can we accomplish right now, what groundwork can we lay for the future, and what are we going to be able to deliver for our communities?"

She said she expect to be named to two committees: infrastructure and armed services.

Meanwhile, Gina Ortiz Jones, running for the U.S. House in Texas’ 23rd district, is still awaiting a final decision in a race that remains too close to call, as is Kyrsten Sinema, who is running for the U.S. Senate, out of Arizona.

Republicans filed a lawsuit Wednesday night to challenge the way some counties in the state count mail-in ballots, as election officials began to slowly tally more than 600,000 outstanding votes to determine a winner between Sinema and her opponent, Republican Rep. Martha McSally.
