Biden angers GOP associating 'garbage' with Trump supporters

An election worker in Miami-Dade County, Florida, was fired after a sealed bag of ballots fell out of a truck, according to election officials.

The Miami-Dade County Elections Department said in a statement Tuesday that the worker forgot to lock the back of a truck and as they drove off, one sealed bag fell out, containing completed ballots from early voting. Residents who observed the incident in real time recovered the bag and drove the items to a local police station.

Despite the incident occurring due to human error, the employee was terminated, the county officials said. All the ballots were accounted for.

“While unintentional, the Elections Department has a zero tolerance for error and therefore the employee was terminated,” the statement said.

President Joe Biden, during a stop at a local ice cream shop in Maryland, told ABC News' Justin Gomez he will be tuning into Harris' speech tonight at the Ellipse.

When asked why he is not attending, Biden responded: "Because it's for her. Because it's her night."

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.

The Harris campaign announced Jennifer Lopez will give remarks in Las Vegas on Thursday. The event will also feature a performance by Maná.

Lopez was one of several Hispanic celebrities to show support for Harris this week after comedian Tony Hinchcliffe called Puerto Rico a "floating island of garbage" at Trump's rally at Madison Square Garden.
