Biden angers GOP associating 'garbage' with Trump supporters

Thousands of supporters gathered in anticipation of Vice President Kamala Harris' closing argument on the Ellipse in Washington D.C.

Asked what the Harris-Walz ticket should do to appeal more to young men, 21-year-old Ramiro Paz Lopez told ABC News that men were the ones who needed to change their behavior.

"I think men just have to listen. I think Kamala and Walz are presenting their message pretty strongly, and I just think men just have to listen and go away from their bubble and just be willing to hear other points of views," he said.

Grace Ledford, a 13-year-old attendee, told ABC News she left her hometown of Champaign, Illinois, at 1:30 a.m. and boarded a flight at 6 a.m. to make it to Washington, D.C. specifically for the Harris rally on Tuesday.

Though she is too young to vote, Ledford expressed how "excited" she was to witness her first rally, explaining how she and her dad lined up over five hours in advance.

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."

In the battleground state of Pennsylvania, election officials have been preparing for months for millions of residents to cast their highly anticipated votes.

But those election officials have also quietly been preparing for another possibility: an onslaught of litigation that could flood the courts on Election Day and beyond.

"We are the biggest swing county in the biggest swing state, so we are very conscious of the fact that we have a lot of eyes on us," Bob Harvie, the Democratic vice chair of the Bucks County Board of Commissioners, said in an interview with ABC News.

Bucks County -- a Philadelphia suburb that former Trump narrowly lost by less than a percentage point in 2016 and by about 5% in 2020 -- has been sued 11 times since the 2020 election, according to Harvie.

Now they are "bracing" for a repeat, he said.

Gov. Tim Walz said Tuesday that Harris' speech at the Ellipse would be "spectacular," while adding that it isn't "by chance" that she's delivering her campaign's closing message there.

"Vice President is going to give a spectacular speech tonight on the Ellipse, and it's not by chance that it's there, because she's going to highlight the promise of America versus the chaos," he said at Iron Black Coffee Co. in Columbus, Georgia, where he was meeting with the Educators for Harris-Walz coalition.
