Midterm elections live updates: Supreme Court denies Trump bid to segregate California votes

Just one day before the high-stakes midterm elections, President Donald Trump on Monday touted his renovations of the Lincoln Memorial Reflecting Pool -- from the granite to the new pipes and "soft dark blue" of the new paint.

Trump claimed he has fixed 2,300 lighting fixtures around Washington, renovated 83 statues and monuments, multiple fountains and his brand new White House helipad. Those details from Trump all came before he mentioned Tuesday’s midterms, which he did 23 minutes into his speech.

In mentioning the midterms, Trump once again attacked Democrats.

"As you know, this is the last day before the midterm elections, the most important midterm, I believe, in our lifetime," said Trump, who delivered the remarks in front of the newly reopened Reflecting Pool.

The president, who noted the uphill battle he faces in efforts to keep control of Congress, said that his party "gave this a very strong shot."

"Because if the people that voted for me and voted in the last election where we had such a great victory, if they go out and vote, just a good portion of them, we will win in a landslide. Now, that doesn't happen, because usually whoever the sitting president is, Republican or Democrat, good or bad, good president, great president, bad. For some reason, the sitting president doesn't win the midterms, but we gave this a very strong shot," Trump said.

Vice President JD Vance on Monday delivered his closing midterm election remarks in his home state of Ohio, where his political career began and where some of the most critical races are being decided, emphasizing the importance of this year's election cycle.

"I want to remind you that we are on the eve of one of the most important -- I would actually say the most important midterm election of my lifetime -- and I am closing out this midterm campaign right where it all started for me, the great state of Ohio, because I know you're going to choose right tomorrow," Vance said.

The state is home to high-stakes Senate and House races that could determine control of Congress. Also the state's gubernatorial election has drawn nationwide interest.

Vance urged Ohioans to cast their ballots on Tuesday for Republican Senate candidate Jon Husted and Republican gubernatorial candidate Vivek Ramaswamy.

"The only game in town for low taxes, for common sense and for patriotic American values, it's Vivek's party. It's John's party. It's the Republican Party. And don't forget it tomorrow,” Vance said.

As Americans prepare to vote in Tuesday's midterm elections, rising healthcare costs are among the top financial and economic concerns, according to recent polling.

A quarter of voters say they are "very worried" about being able to afford healthcare costs and more than one-third say they are "somewhat worried," according to a KFF poll earlier this month.

Those who get their health insurance through the Affordable Care Act (ACA) saw their average monthly benchmark premium jump from $497 per month in 2025 to $625 in 2026, according to KFF, particularly after enhanced premium tax credits expired at the end of last year.

"At this point in time, I am not seeing that there's going to be any sort of magic bullet in the short term to bring costs down," Sabrina Corlette, a research professor, founder and co-director of the Center on Health Insurance Reforms at Georgetown University McCourt School of Public Policy, told ABC News.

One day before ballot counting begins in California, the DOJ has filed a last-minute appeal with the U.S. Supreme Court seeking an injunction ordering the segregation of 20,000 ballots from suspected noncitizen voters.

Solicitor General John Sauer reiterates the familiar arguments about the need to investigate -- writing, "California and the United States disagree about the likely unlawfulness of the ballots at issue. These dueling allegations can and should be investigated. In the meantime, however, an interim injunction is necessary to preserve the relative positions of the parties until a trial on the merits can be held. To that end, the Court should issue a limited injunction directing California to stop commingling suspected illegal ballots with legal ones pending completion of the United States’ appeal to the Ninth Circuit and further review in this Court."

The high court will likely ask for a response from the state but it remains unclear -- if not unlikely -- that the justices will act on this.
