Only about 1,000 votes separate Democratic candidate Scott Colom and Republican Sen. Cindy Hyde-Smith in Mississippi’s closer-than-expected race for U.S. Senate.

With 96% of the expected vote reporting as of 10 p.m. ET on Wednesday, Colom had 49.0% of the vote (464,926 votes), followed by Hyde-Smith with 48.9% of the vote (463,788).

Colom only leads Hyde-Smith by 1,138 votes.

A new batch of votes added to the count Wednesday evening slightly grew Colom's earlier razor-thin lead.

Independent candidate Ty Pinkins, who said on CNN on Wednesday that he wants Colom to win, followed with 2.1% of the vote (19,934 votes).

A close-race audit has been initiated for six races in Kansas, including the competitive gubernatorial race between Democratic state Sen. Cindy Holscher and Republican state Senate President Ty Masterson, according to the state's secretary of state office.

With 99% of the expected vote in, Holscher has 50.3% compared to 49.7% for Masterson. The audit involves reviewing ballots in 10% of precincts in each county, according to the secretary of state's office.

Holscher already declared victory with a statement posted to X on Wednesday morning.

"The people of Kansas made their voices heard, and I’m deeply honored by the trust Kansans placed in me to serve as your next governor. Whether I earned your vote or not, I will work for you," she wrote.

However, Masterson has not conceded, according to a spokesperson for his campaign. He wrote on X that it was "a difficult night," but "the margin is narrow enough that Kansas law calls for another look, and we'll let that process finish."

Rep. Tom Emmer, the current House majority whip, is facing a challenge from Rep. August Pfluger of Texas, the outgoing chairman of the Republican Study Committee, to become minority whip, according to letters both lawmakers sent to colleagues Wednesday that were obtained by ABC News.

"There is no sugarcoating the failure we just experiences," Emmer of Minnesota wrote. "We lost, and I take that loss personally, both as a competitor and a member of this team."

Emmer said Republicans "must continue to fight" and touted his ability as whip for bringing members together across the conference.

Pfluger said he is running to be minority whip, "because I believe that I am capable and can be trusted to implement the changes this team needs."

"From day one in Congress, I have devoted myself towards helping others and that is exactly what I will continue to do in this role," he wrote.

Pfluger said Republicans must prioritize a strategy to win back the majority in 2028.

In a letter to his colleagues on Wednesday, Democratic Rep. Hakeem Jeffries formally announced his bid to be the next speaker of the House.

“I write to humbly request your support in connection with my candidacy to serve as the next Speaker of the House of Representatives,” Jeffries wrote in the letter, obtained by ABC News.

House Democrats will hold leadership elections on Nov. 18, with members voting behind closed doors. Jeffries only needs a simple majority of the caucus to secure the nomination. To be formally elected House speaker, Jeffries needs 218 floor votes to receive the gavel in January.

Jeffries, who is poised to become the first Black speaker of the House, outlined what Democrats will focus on under his leadership if elected as the 57th speaker.

“In the new Congress, we will aggressively fight for an affordable America. Life is way too expensive, and millions of hardworking taxpayers are drowning in this failed economy. As part of our effort to turn things around, every single member of our majority will play a meaningful role. My goal is to empower you to act decisively in three key areas: (1) Affordability (2) Accountability and (3) American Values,” Jeffries wrote.

Florida Gov. Ron DeSantis described Tuesday's election results, which saw Democrats make massive gains in states including Texas, Iowa and South Carolina, as a "meteor strike," arguing that even a “wave” fails to capture the scale of the Republican losses.

“Last night, we witnessed, to call it a wave, I don't think would be fully accurate. It's the political equivalent of a meteor strike that went all around the United States, blue states, red states, everything in between, and the one state that was able to hold the line and withstand that is right here in the free state of Florida,” DeSantis said Wednesday in Florida.

DeSantis touted Republican candidates' success in Florida, but victory margins in many races were much closer than in previous years, as the Florida governor mentioned later on in his remarks.

DeSantis, who has not ruled out another presidential run, did not mince his words about last night’s election results for Republicans across the country, calling it a “close to an extinction-level event” for the party.

“Let's just be clear about what happened last night. This is close to an extinction-level event for Republicans in many parts of the country, as we have seen, probably in the last 100 years," he said.
