President Joe Biden delivered a solemn Oval Office address Wednesday that laid out in the clearest terms yet why he abandoned his reelection campaign.

He wanted to send an unmistakable warning about Republican presidential nominee Donald Trump while anointing Vice President Kamala Harris as his natural successor, without invoking an overtly political tone that would have been out of step in the official setting of the White House. He was determined to show that he would not act like a lame-duck president, outlining an ambitious agenda that underscored his resolve to continue building on his legacy.

Here are key takeaways from Biden’s address:

He warned about Trump — without naming him

Biden did not mention Trump, his former Republican opponent, in his 10-minute Oval Office address — but he didn’t have to. The remarks were imbued with a deep sense of urgency about what the outgoing president saw as the stakes of the election.

The early part of his address sketched the choices that faces voters in November — a contrast Biden himself had hoped to make during a reelection campaign that he ultimately decided he could not continue.

“Americans are going to have to choose between moving forward or backward, between hope and hate, between unity and division,” Biden said. “We have to decide — do we still believe in honesty, decency, respect, freedom, justice and democracy.”

That last item — democracy — and defending it is “more important than any title,” Biden said.

Biden outlined a hefty to-do list for his final months 

The president says he’s going to keep working over his final six months in office. He’s seeking to make the case for his legacy of sweeping domestic legislation and the renewal of alliances abroad.

His to-do list was full of weighty issues. He said he’d work to end the war in Gaza, bring home the hostages and try “to bring peace and security to the Middle East and end this war.” Biden meets Thursday with Israeli Prime Minister Benjamin Netanyahu.

He’s going to continue to work to lower costs for families and defend personal freedoms, keep calling out “hate and extremism” and push to end gun violence.

He also said he would continue to work on his initiative to end cancer as we know it and push for Supreme Court reforms.

“I’m going to keep working,” he said.

He is willingly handing off power to a new generation

Biden finally understood what Democrats had been telling him — that it was time to hand off power to a younger generation — and he embraced it, calling for “fresh voices, yes, younger voices” in politics.

“I’ve decided the best way forward is to pass the torch to a new generation. It’s the best way to unite our nation,” he said, even as he believed his presidency was deserving of a second term.

For months, Biden insisted that only he could go up against Trump and win. But that changed following his debate with Trump on June 27, when he spoke haltingly, lost his train of thought and failed to fact-check the former president’s falsehoods. The performance raised a chorus of questions about his age and ability to do the job another four years and pushed Democrats to increasingly call for him to step aside. The standoff dragged for 24 days before Biden yielded, saying he needed to unify his party.

The tone and setting were solemn

Biden is not a stranger to the sober address, delivering remarks on weighty matters such as the fate of democracy and voting rights at historically significant landmarks across the country and around the globe.

But Biden has used the formal trappings of an Oval Office address — a tool used by presidents in times of national crisis or to capture a key moment in history — sparsely, with Wednesday’s speech marking just the fourth time that he has sat behind the Resolute Desk to speak directly to the nation.

His tone was solemn, the delivery careful and deliberate. He was surrounded by family and close aides as he gave an address willingly relinquishing power — one that no politician wants to make.

“The great thing about America is here, kings and dictators do not rule — that people do,” Biden said as he closed his address. “History is in your hands. The power is in your hands. The idea of America lies in your hands.”

Biden made a subtle push for his vice president
In the official setting of the Oval Office, Biden steered clear of overt political talk. But he still praised Vice President Kamala Harris as “tough” and “capable,” and gave a not-so-subtle push to voters.

“She’s been an incredible partner for her leadership, for our country,” he said. “Now the choice is up to you, the American people. ”

First lady Jill Biden posted a hand-written note after the president’s speech thanking “those who never wavered, who refused to doubt.” She thanked supporters for putting their trust in the president. “Now it’s time to put that trust in Kamala.”

Biden, aides say, knows that if Harris loses, he’ll be criticized for staying in the race too long and not giving her or another Democrat time to effectively mount a campaign against Trump. If she wins, she’ll ensure his policy victories are secured and expanded, and he’ll be remembered for a decision to step aside for the next generation of leadership.
