Biden and First Lady Jill Biden left the White House just a few moments ago for the short drive up Pennsylvania Avenue to the U.S. Capitol, where the president will deliver his first State of the Union address tonight.

Biden did not respond to a shouted question asking if Russian President Vladimir Putin has committed war crimes in Ukraine.

Biden tonight will touch on his plan to address crime and make the case for more community-based policing, rather than defunding the police, a White House official told ABC News.

"He'll make clear that the answer is not to defund the police, it’s to put more police -- with better training and more accountability -- out to take back our streets and make our neighborhoods safer," the White House official said. "And he’ll talk about the steps his administration has taken -- and will continue to take -- to advance that accountability and rebuild trust between law enforcement and the communities they serve."

Biden will also call on Congress to address gun violence, and pass "common-sense" gun violence legislation that will save lives, according to the official.

The nation's capital has ramped up security ahead of Biden's first State of the Union address tonight.

Up to 700 National Guard troops have been made available to assist local law enforcement, and a controversial inner-perimeter fence once again surrounds the U.S. Capitol.

The U.S. Capitol Police have also been working in tandem with local, state and federal law enforcement agencies on a "security plan to prevent any disruption to the important work of Congress," Capitol Police Chief Tom Manger said in a statement earlier this week.

"Given the current state of affairs, both foreign and domestic, tonight is a big night for the president," writes FiveThirtyEight politics reporter Alex Samuels.

President Joe Biden's 9 p.m. ET speech, to be carried live on national television and seen around the world, will be delivered just days after Russia invaded Ukraine -- and days after he nominated the first Black woman to sit on the Supreme Court.

But he'll also be speaking to Americans suffering from historic inflation as the nation continues to emerge from the coronavirus pandemic.

With his job approval at an all-time low of 37%, Biden faces the difficult task of balancing their pain with his desire to reap the political benefits of his legislative wins so far -- a massive COVID relief package and a once-in-a-generation investment in the nation's infrastructure -- while also demonstrating his leadership on one of the greatest threats to European stability since World War II.
