The U.S. Postal Service issued an alert to voters who are planning to mail an absentee ballot and urged them to send them through the mail on Tuesday.

Although the USPS said it is "ready to successfully deliver the nation's mail-in ballots for voters who choose to use us to vote," it is anticipating an uptick of ballots in the mail over the coming days.

"We continue to recommend that it is a good common-sense measure for voters who choose to mail in their ballots to do so before Election Day and at least a week before their election office needs to receive them. If a ballot is due on Election Day, the Postal Service recommends mailing the ballot by this Tuesday (October 29)," the agency said in a news release.

The USPS said 99.9% of ballots were delivered within a week in 2020 and 98.3% of ballots were delivered within three days.

The USPS said it has undertaken "extraordinary measures" that it has taken in past elections, including extra deliveries and collections, special pickups, specialized sort plans at processing facilities to expedite delivery to boards of elections, and local handling and transportation of ballots.

Vice presidential nominee Ohio Sen. JD Vance, Donald Trump's running mate, will sit down for an interview with Joe Rogan on Wednesday for his podcast, a spokesperson for Vance told ABC News.

The interview will take place in Austin, Texas, and is expected to drop later this week.

Vance's interview with Rogan comes after Trump sat down with Rogan last week for a three-hour interview.

Rogan posted on X on Monday that Vice President Harris' campaign offered to do his podcast on Tuesday on the road, but that he didn't want to travel from his studio.

The former president denied knowing the comedian who made a slew of racist, sexist and vulgar comments at his rally at Madison Square Garden, ABC News Senior Congressional Correspondent Rachel Scott reports.

That comedian, Tony Hinchcliffe, drew headlines in part for calling Puerto Rico an "island of floating garbage."

"I don't know him, someone put him up there. I don't know who he is," Trump told ABC's Scott.

Trump also insisted he didn't hear any of the comments, even as they've been played on television and written about extensively. When asked what he made of them, he did not take the opportunity to denounce them, repeating that he didn't hear the comments.

His campaign has said the comedian's comments don't reflect the views of Trump or the campaign.

Trump also expressed confidence that he will win the White House with just a week to go.
