Biden reiterated his calls for free access to pre-school for 3- and 4-year-olds, saying children who attend early pre-school are more likely to finish high school and go onto receive a college degree.

He also said he wanted to expand tutoring and summer learning time and "see to it that every child learns to read by third grade."

"While we’re at it I want to give public school teachers a raise," he said.

Biden vowed to protect the Affordable Care Act, aka Obamacare, which he said provides health insurance to more than 100 million people who would otherwise be denied it due to pre-existing conditions.

"But my predecessor and many in this chamber want to take that protection away by repealing the Affordable Care Act," he said, as some in the chamber booed. "I won’t let that happen!"

"We stopped you 50 times before and we will stop you again!" he continued.

Republicans have for years tried and fail to repeal and replace the law, which has grown increasingly popular with the public.

In addition to protecting Obamacare, Biden said he wants to expand it by making permanent tax credits set to expire next year that save families $800 annually.

Biden touted efforts to make housing more affordable, including helping Americans have enough money to obtain a federally backed mortgage.

"My administration is also eliminating title insurance on federally backed mortgages. When you refinance your home, you can save $1,000 or more as a consequence," he said.

"I know the cost of housing is so important to you. As inflation keeps coming down, mortgage rates will come down as well…but I'm not waiting. I want to provide an annual tax credit that will give Americans $400 a month for the next two years as mortgage rates come down to put toward their mortgage when they buy their first home or trade up for a little more space."

Biden took a moment to introduce United Auto Workers (UAW) President Shawn Fain, who endorsed him for reelection, while speaking about the power of unions in America.

Biden praised unions for building up the middle class.

"Wall Street didn't build America. They’re not bad guys, they didn't build it though," Biden said. "The middle class built the country and unions built the middle class!"

Addressing the Nation, Biden said, "I say to the American people, when America gets knocked down, we get back up! We keep going! That's America!"

Hi, I’m Monica Potts, a senior political reporter at 538. I’ll be watching the State of the Union and helping provide analysis and commentary about some of the themes from Biden’s speech. I’ll be especially interested in what he has to say about abortion, foreign policy, democracy and the economy. As my ABC News colleagues have noted, the night is really a sort of campaign kickoff event, and how he frames those issues could preview how he plans to talk about them with voters.

I’ll be able to provide context on how voters think about those issues as well. While my colleagues at 538 and I know that the State of the Union itself tends not to move the needle politically, the speech can tell us where Biden plans to focus his efforts this election year. It’s also an opportunity for Biden to assuage concerns from his own voters and inspire them to vote in November. The presidential race has the potential to be as close as the last two, so he’ll need it if he wants to win.
