US President-elect Donald Trump used the last rally before his inauguration to once again celebrate his election victory, declaring on Sunday: “We won” to a crowd celebrating his return to the White House and projecting a defiant optimism despite deep national political divisions.

“Tomorrow, at noon, the curtain closes on four long years of American decline and we begin a brand new day of American strength and prosperity, dignity and pride,” Trump told supporters, adding: “We not only won the mandate, but we built a new American majority that will lead our country to success for generations to come.”

Fans filled nearly the entire 20,000-seat Capital One Arena in Washington, DC to hear Kid Rock perform, who performed All summerdespite the cold mix of rain and snow falling outside. Singer Lee Greenwood, whose God bless USA was Trump’s re-election campaign anthem.

“Our hero. A man who never gave up on the American people and we the people never gave up on him,” actor Jon Voight told the crowd.

Stephen Miller, Trump’s choice for deputy chief of staff and a key architect of the administration’s promised hard-line immigration policy, promised that “justice is coming.”

“We’re going to get our country back and our democracy back soon,” Miller said, adding, “Donald J. Trump is going to save this country.”

Trump has promised to sign a number of executive actions, including the US-Mexico border policy. Sunday was his first full day in Washington and gave the president-elect a chance to energize core supporters before the official fanfare of Inauguration Day.

Trump had a private breakfast with Republican senators at Blair House, the president’s official guest residence across Pennsylvania Avenue from the White House, and later posed for a picture with 10 Republican senators and his new chief of staff, Susie Wiles.

Unlike when Trump helped inspire crowds of his supporters to storm the Capitol and try to retain power in 2021 after losing to Democrat Joe Biden, officials did not expect mass protests, riots or violence. Instead, cheering crowds celebrated Trump’s second term and MAGA’s total control of the Republican Party.

Many arrived from all over the country and were dressed in their finest clothing, including fur coats. Trump supporters filled parties at hotels and restaurants across Washington. As they moved between celebrations, some could be heard chanting “MAGA” or simply saying it as a greeting to fellow revelers.

The atmosphere was an incredible turnaround from four years ago, when Trump left the capital in disgrace and skipped the inauguration of his successor. He swept through the 2024 Republican presidential primary and won in November with an electoral margin not seen since Barack Obama was re-elected in 2012.

Yet even with that comfortable victory and his party in full — albeit narrow — control of Congress, the president-to-be is one of the most polarizing figures in US history, with almost as many fierce detractors as ardent supporters. That means it could be difficult for Trump to deliver on post-election promises to promote bipartisanship while healing policy differences.

He insisted that unity would be the theme of his inauguration speech on Monday, along with strength and fairness, but also spent months as a candidate saying that if elected he would seek retribution against political enemies.

“January 20th can’t come soon enough!” Trump posted on his social network. “Everybody, even those who initially opposed the victory of President Donald J. Trump and the Trump administration, just want it to happen.”

With cold temperatures expected on Monday, Trump ordered most outdoor events to be moved indoors on Monday, and officials held a rehearsal for his inauguration on Sunday in the US Capitol Rotunda, which holds only 600 people compared to more than 250,000 ticketed guests to watch the inauguration from the Capitol grounds.
