2024 election updates: With 1 week to go, Harris speaks in Washington, Trump stumps in Pennsylvania

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 U.S. Supreme Court denied Tuesday evening Robert F. Kennedy Jr.'s request for an injunction ordering the Wisconsin Election Commission to use stickers to cover his name on the state's presidential ballot.

The court did not elaborate on its decision in a single-sentence order and there were no noted dissents.

The court also denied Kennedy's appeal that sought to make Michigan reprint election ballots without his name.

The court did not elaborate on the decision, however, Justice Neil Gorsuch, in the sole noted dissent, indicated that he would have granted the injunction.

Gorsuch cited as his rationale the reasons given by several dissenting conservative members of a federal appeals court panel which had earlier weighed the case.

That minority in the appeals court had concluded that denying a federal candidate the ability to withdraw from the ballot may have infringed on his First Amendment rights.

Vice President Kamala Harris will spend election night at Howard University, her alma mater, two sources familiar with the planning told ABC News.

Harris graduated from the Washington, D.C., HBCU in 1986.

She used the campus to practice for ABC News's debate in August and occasionally worked from an office on campus while campaigning during her 2019 bid for the presidency.

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.
