2024 election updates: Trump and Harris bring their campaigns to the battleground state of Wisconsin

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.

After making a surprise appearance at her husband's Madison Square Garden rally on Sunday, Melania Trump spoke out on "Fox and Friends" on Tuesday, fiercely defending him against reported comments that he had expressed admiration for Hitler.

"He is not Hitler and his supporters stand behind him because they want to see the country successful. We see what kind of support he has," she said of the former president.

Donald Trump has falsely claimed that Vice President Kamala Harris called him Hitler (she cited reports that Trump's former chief of staff John Kelly said he had praised Hitler for doing some "good things" and wanted generals like Hitler's).

Melania Trump called the criticism "terrible."

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.

Joe Torres has the details on the comments that sparked backlash.

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.

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

Despite ongoing claims of voter fraud and ballot mismanagement from former President Donald Trump and his allies, 86% of registered voters in a new ABC News/Ipsos poll say they personally are prepared to accept the outcome of the 2024 presidential election as legitimate, regardless of which candidate wins.

Two-thirds, however, believe Trump is not prepared to accept the outcome as legitimate. Fewer than half as many, 30%, say the same of Vice President Kamala Harris.

Even among Trump's supporters, 81% say they are prepared to accept the election outcome as legitimate. That rises to 92% of Harris supporters in this poll, produced for ABC by Langer Research Associates with fieldwork by Ipsos.
