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.

Ahead Biden's first State of the Union address, House Republicans claimed the "state of our union is in a crisis," which they say is directly caused by Biden and House Democrats' "failed far-left socialist agenda."

"Tonight, President Biden will try to rewrite history of the past year and pass the buck instead of taking responsibility for the failures of his radical far-left Democrat agenda," the third-ranking House Republican Rep. Elise Stefanik said at a press briefing Tuesday.

Republicans are holding Biden personally responsible for several issues, from inflation to high gas prices to supply chain issues to the invasion of Ukraine.

"The war on Ukraine represents one of the greatest foreign policy failures in modern history," Stefanik said. "For months, President Biden failed to engage in meaningful deterrence against Russian aggression."

Ukrainian-American Rep. Victoria Spartz gave an emotional plea calling for the Biden administration to do more to help Ukraine.

"This is not a war, this is a genocide of the Ukrainian people," Spartz, who represents Indiana, told reporters. "They want to be free people. They want to be with the West."
