Harris will go after Trump in her speech in Houston, Texas, on Friday night that will focus on reproductive rights.

"The Attorney General of Texas is suing the United States Government so that Texas prosecutors can get their hands on the private medical records of women who leave the state to get care," Harris will say, according to released excerpts of her speech.

"So, see what is happening: Donald Trump won’t let anyone see his medical records. But these guys want to get their hands on yours? Simply put: They are out of their minds," she will say.

The vice president will reiterate her campaign pledge to push Congress to pass a bill restoring Roe v. Wade if elected.

"We are fighting for an America where, no matter who you are, or where you live, you can make that decision based on what is right for you and your family," Harris will say.

Speaking to reporters before her event later today in Houston, Harris said she wanted to address Trump's comment that America has become a "garbage can" and "dumping ground" for migrants from around the world.

"You know, it's just another example of how he really belittles our country," Harris said. "This is someone who is a former president of the United States, who has a bully pulpit, and this is how he uses it, to tell the rest of the world that somehow the United States of America is trash."

"And I think, again, the president of the United States should be someone who elevates discourse and talks about the best of who we are and invest in the best of who we are, not someone like Donald Trump, who is constantly demeaning and belittling who the American people are," the vice president added.

Trump's comments are the latest example of his anti-immigrant rhetoric.

In what could have been his final financial event of the campaign, Tim Walz, at a fundraiser in Pennsylvania, said it was now time to use all that money to focus on the ground game.

"Now it's time to execute ... Never in my lifetime, would I have believed that the choice would be so stark," he said.

The Harris campaign and the Democratic National Committee entered the final three weeks of the election with a clear cash advantage over the Trump campaign and the Republican National Committee, latest FEC records show.

As of Oct. 16, the Harris campaign, the DNC and their joint fundraising committees reported having nearly $270 million in cash on hand compared to $202 million the Trump campaign, the RNC and their joint fundraising committees had in the bank, the new filings show.

The Trump campaign committee, in particular, had $36 million in the bank as of Oct. 16 compared to the Harris campaign committee having $119 million in cash on hand.

Trump on Friday reposted his earlier message promising, before any evidence of fraud, to prosecute and deliver long prison sentences for election workers and others who he deems to have cheated during November's election.

"Please beware that this legal exposure extends to Lawyers, Political Operatives, Donors, Illegal Voters, & Corrupt Election Officials," Trump wrote on his social media platform. "Those involved in unscrupulous behavior will be sought out, caught, and prosecuted at levels, unfortunately, never seen before in our Country."

Election officials had called such a threat "dangerous" given the heightened threat environment.

"It makes me concerned that this will set other people off. I think the one thing that we've seen before is that words have consequences and meaning," Arizona Secretary of State Adrian Fontes told ABC News last month.

"And while we are concerned, we are also prepared. Elections officials across the country have been working with local, state and federal law enforcement agencies to monitor and track threats, to make sure we're keeping our voters safe and make sure we're keeping our elections officials safe," Fontes said.
