One of the upper levels has mostly filled in during musical performances. The uppermost level is still almost completely empty, though people are still trickling in. As people entered, they mentioned long lines outside the arena.

A series of speakers and performances are still expected ahead of Trump's speech tonight. Trump rallies typically have long preprograms leading up to his speeches.

Kid Rock, a prominent Trump supporter who performed at star-studded fundraisers during Trump’s campaign and took the stage at the Republican National Convention in Milwaukee last year, is onstage at Capitol One as Trump’s rally gets underway.

A recorded clip of Trump addressing his supporters briefly interrupted the performance. 

Trump’s rally has kicked off at Capital One Arena with a national anthem performance by singer Kiley Dean. There’s a long list of speakers before Trump himself takes the stage.

MyPillow founder and Trump ally Mike Lindell is here and taking photos with Trump supporters on the floor of Capitol One Arena.

Lindell has been a longtime Trump supporter. In the wake of Trump's 2020 loss in that year's presidential election, Lindell falsely claimed that he actually won. Lindell was hit with a defamation lawsuit by a voting machine company that said he falsely accused it of rigging the election against Trump.

With about 10 minutes to go before Trump’s inauguration-eve rally begins with preprogram speakers, most of the upper levels at Capital One Arena remain empty, with seats still available in the lower bowl.

Capital One Arena typically seats 20,000, and with the seating arrangement on the floor, it could likely accommodate another thousand or so more today.

Shortly after their visit to the Tomb of the Unknown Solider, Trump and Vance visited the cemetery's Section 60, which is largely reserved for the deceased veterans of the Iraq and Afghanistan wars.

The president-elect and vice president-elect are visiting four graves with honored guests and their families.

This part of the cemetery was the site of controversy in August, when Army officials accused Trump's campaign aide of "abruptly pushing aside" an employee who was trying to enforce restrictions on taking photos and videos in Section 60.

Vice President-elect JD Vance met with Chinese Vice President Han Zheng in Washington ahead of the inauguration, the Trump transition team said in a press release.

The two "discussed a range of topics including fentanyl, balancing trade, and regional stability," the release said.

A spokesperson for the Chinese Embassy in Washington told NBC News last week that Han is attending Trump's inauguration as "President Xi Jinping’s special representative." His attendance marks the first time a senior Chinese leader will attend a U.S. president's inauguration.

On his final full day in office, Biden spoke to congregants at a church in Charleston, the same church where he spoke in February 2020, during his presidential campaign.

"On my final full day as president, of all the places I wanted to be was back here with you,” Biden told worshippers.

Trump and Vance have arrived at Arlington National Cemetery to lay wreaths at the Tomb of the Unknown Soldier.

They're accompanied by their wives — Melania Trump and Usha Vance — as well as several of Trump's Cabinet picks including director of national intelligence pick Tulsi Gabbard, defense secretary pick Pete Hegseth and secretary of state pick Sen. Marco Rubio, R-Fla.

Members of Trump's family, including his children Ivanka, Donald Jr. and Eric, are also in attendance.
