2024 election updates: Trump and Harris bring their campaigns to the battleground state of Wisconsin

The backdrop to Harris' closing argument speech on Tuesday will be the office she hopes to hold: The White House.

The event is thick with symbolism. Held on The Ellipse, the park just south of the White House, the event will represent Harris' clearest attempt to show why she deserves to be the person sitting in the Oval Office next year. The site of the speech also harkens back to the January 6, 2021, attack on the Capitol: It is where Trump gave a speech filled with lies about the election immediately beforehand.

Harris specifically mentioned in interviews before her remarks on Tuesday that the backdrop was picked to help voters envision having her in the Oval Office instead of Trump.

People attending the event have been standing in line for hours and are now waiting for Harris to take the stage. The back of the stage is lined with American flags, and large signs that read "Freedom" in block letters flank the set-up.

Federal agency transition members met with representatives from both the Harris and Trump campaigns, sources with knowledge of the meetings confirmed to ABC News.

Up until now, the Trump team has been very reticent to conduct any formal meetings with Biden White House staff and had blown past ethics and funding agreement deadlines.

A spokesperson for the White House confirmed the meeting, which took place in the Eisenhower Executive Office Building.

"The ATDC has been meeting regularly for months to prepare for a transition, and the meeting this week included representatives from both transition teams," the spokesperson said in a statement. "The meeting focused on post-election readiness to ensure agencies and the transition teams are ready to execute responsibly and efficiently."

Former President Donald Trump was back in Pennsylvania on Tuesday, where he held a roundtable in Drexel Hill with Mike Huckabee.

He spoke about what he believes are the most important issues in the upcoming election.

"Every poll has inflation and economy as the number one thing, and the third is the border. I think inflation is horrible. I think it's wrong. I think the number one is the border," he said.

1 week until Election Day: Trump holds roundtable in Drexel Hill, set to rally in Allentown

Trump is also expected to hold a rally in Allentown Tuesday night, which has a majority Latino population.

That remains an important factor as the former president and his campaign try to distance themselves from disparaging comments made about Puerto Rico by a speaker at his rally in New York City over the weekend.

On Tuesday morning at Mar-A-Lago, Trump called the rally at Madison Square Garden a "love fest."

He also held a rally on Monday on the campus of Georgia Tech, in Atlanta, after attending the National Faith Summit. There, Trump blasted the Democrats for using what he says is disgusting rhetoric, and told the crowd that his administration would stop inflation and bring back the American dream.

According to excerpts of Harris' speech, as prepared for delivery, she will go after Trump for the dark language he has used to describe his political opponents and pitch herself in contrast as someone who will govern for all Americans.

"Donald Trump intends to use the United States military against American citizens who simply disagree with him. People he calls 'the enemy from within.' This is not a candidate for president who is thinking about how to make your life better," she will say.

Harris will describe Trump as "unstable" and "obsessed with revenge."

"But America, I am here tonight to say: that's not who we are," Harris will say.

She will then pivot to her optimistic plan for improving people's lives.

"I offer a different path. And I ask for your vote. And here is my pledge to you: I pledge to seek common ground and common sense solutions to make your lives better. I am not looking to score political points. I am looking to make progress," she will say.
