Election 2024 updates: Harris headed to Milwaukee rally Tuesday

(CHICAGO) — Vice President Kamala Harris on Friday unveiled her economic platform, her first major policy rollout since becoming the Democratic nominee.

Former President Donald Trump on Thursday held a press conference in Bedminster, New Jersey, where he said he’s “entitled” to insult his Democratic opponent because he doesn’t respect her and attacked her record on the economy.

Here’s how the news is developing:

Harris headed to Milwaukee rally tonight

Democratic candidate for president, Vice President Kamala Harris, is set to speak at a rally in Milwaukee on Tuesday, according to her campaign.

Gov. Tim Walz, Harris’ vice presidential running mate, will be in attendance, the campaign confirmed. Also expected at the event are Congresswoman Gwen Moore, Milwaukee Mayor Cavalier Johnson, members of the Milwaukee Bucks franchise, including Khris Middleton and President Peter Feigin, and labor leaders.

Harris and Waltz appeared at the DNC in Chicago on Monday night, where Harris surprised delegates by taking the stage early in the night for a brief speech.

Tuesday’s rally, which is being held at the Fiserv Forum in Milwaukee, is aimed at energizing Wisconsin voters, the campaign said.

Iran denies involvement in attempts to hack Trump, Biden campaigns

Iran is denying reports it was involved in attempts to hack the presidential campaigns of former President Donald Trump and President Joe Biden, the latter of which while he was still in the race.

In a statement, the Permanent Mission of the Islamic Republic of Iran to the United Nations, said that reports of attempted hacking, which came from Google and Microsoft, are “unsubstantiated.”

“Such allegations are unsubstantiated and devoid of any standing. As we have previously announced, the Islamic Republic of Iran harbors neither the intention nor the motive to interfere with the U.S. presidential election,” the statement read. “Should the U.S. government genuinely believe in the validity of its claims, it should furnish us with the pertinent evidence—if any—to which we will respond accordingly.”

Bernie Sanders to speak at DNC on ‘lowering health care costs’

Lowering health care costs will be a central theme at the Democratic National Convention this week, campaign and convention officials said on Monday, with Sen. Bernie Sanders (I-Vt.), confirmed as one notable program speaker set to focus upon the issue — specifically on “lowering Rx drug prices” and “taking on Big Pharma.”

Speakers throughout the week like Sanders, California Rep. Robert Garcia, Illinois Rep. Lauren Underwood and New Mexico Gov. Michelle Lujan Grisham will highlight the support of Vice President Kamala Harris and Minnesota Gov. Tim Walz for strengthening the Affordable Care Act, convention officials shared first with ABC News.

In a Friday speech setting out a string of economic proposals, Harris pledged to “lower the cost of insulin and prescription drugs for everyone.” She also said she’d “demand transparency from the middlemen who operate between Big Pharma and the insurance companies, who use opaque practices to raise your drug prices and profit off your need for medicine.”

Harris and Walz debut new campaign buses and kick off tour ahead of DNC

Vice President Kamala Harris and Gov. Tim Walz debuted their new campaign buses Sunday and kicked off a bus tour of southwestern Pennsylvania ahead of this week’s Democratic National Convention.

Upon their arrival on Air Force Two, a few hundred supporters greeted Harris, Walz and their spouses at a hangar where the new were buses parked.

Supporters told ABC News they were thrilled by Harris’ candidacy, with one saying she had not felt this excited about politics in years. Some said they had never volunteered for a campaign before signing up to work on Harris’.

“I was excited about Biden, but I am a million times more excited about Kamala,” Nicole Molinaro, a Pittsburgh-area mom, said. “I think that we need her leadership. We need her intelligence. We need her progressive, you know, stance. I think we need her experience. We need everything about Kamala.”

Another supporter, Edward Freel, said he was unsure about Harris at first, “but then, as I started listening better and following her, [I thought] this woman is going to be good for this country.”

Former Democrat Rep. Tulsi Gabbard will help Trump prepare for presidential debate

Former Democratic Rep. Tulsi Gabbard will assist Trump in preparing for his first debate against Vice President Kamala Harris.

“[Trump] does not need traditional debate prep but will continue to meet with respected policy advisors and effective communicators like Tulsi Gabbard, who successfully dominated Kamala Harris on the debate stage,” Trump campaign National Press Secretary Karoline Leavitt wrote in a statement to ABC News, confirming a development first reported by The New York Times.

Gabbard, a former Democratic congresswoman from Hawaii and a one-time Democratic presidential candidate during the 2020 election, gained brief momentum during her presidential run after challenging Harris on the debate stage on topics like criminal prosecutions.

Since leaving the Democratic Party, Gabbard has been gaining traction among Trump supporters, and more recently she has appeared on Fox and other conservative news outlets attacking Harris.
