Vice President Kamala Harris will on Tuesday hold her first presidential campaign rally in Milwaukee, Wisconsin, according to her campaign.

The Harris campaign signaled in a memo that the vice president would take on former President Donald Trump and his running mate, Sen. JD Vance, on abortion and Project 2025.

The campaign said Harris "is prepared to prosecute the case against Donald Trump -- and there’s no better place to drive this contrast than Milwaukee, Wisconsin."

The rally comes days after Republicans held their nominating convention in Milwaukee, and weeks before the Democrats hold their convention in Chicago.

"Vice President Harris’s visit will highlight the choice facing Wisconsinites: between Donald Trump, the convicted felon who would drag this country backwards, and her brighter vision for the future, where our freedoms are protected and every American has a fair shot," the campaign said in the memo.

Vice President Kamala Harris has raised $100 million since entering the race for president on Sunday, according to her campaign.

The massive haul was raised between Sunday afternoon --when President Joe Biden announced he would step down from the ticket—and Monday evening, the Harris campaign said. The Democratic National Committee and its joint fundraising committees raised the money, the campaign said.

About 58,000 people also signed up to volunteer for the vice president's campaign, a figure that is more than 100 times its average daily signup rate, according to the campaign.

Vice President Kamala Harris has reacted to the news she has secured commitments from enough delegates to become the presumptive Democratic nominee for president.

"When I announced my campaign for President, I said I intended to go out and earn this nomination. Tonight, I am proud to have secured the broad support needed to become our party’s nominee, and as a daughter of California, I am proud that my home state’s delegation helped put our campaign over the top," Harris said in a statement. "I look forward to formally accepting the nomination soon."

The vice president also expressed gratitude for the support she's received from President Joe Biden and those in the Democratic Party who have already endorsed her.

She also drew a contrast between herself and GOP candidate Donald Trump.

"This election will present a clear choice between two different visions. Donald Trump wants to take our country back to a time before many of us had full freedoms and equal rights. I believe in a future that strengthens our democracy, protects reproductive freedom and ensures every person has the opportunity to not just get by, but to get ahead," she said in her statement.

"Over the next few months, I will be traveling across the country talking to Americans about everything that is on the line. I fully intend to unite our party, unite our nation, and defeat Donald Trump in November," her statement concluded.

According to ABC News' reporting earlier on Monday night, Harris secured commitments from enough delegates to become the presumptive Democratic nominee for president if they all honor their commitments when voting.

Vice President Kamala Harris has secured commitments from enough delegates to become the presumptive Democratic nominee for president if they all honor their commitment when voting, according to ABC News' reporting.

Many state parties -- including groups with large delegations such as California and New York -- announced Monday, the day after Harris announced she was running, that all of their delegates would commit to supporting her.

This was significant because the delegates that President Joe Biden accrued during the primaries do not automatically go to Harris, and delegates remain permitted to "vote their conscience."

As of 10:15 PM ET, according to ABC News' reporting, Harris has secured non-binding commitments from at least 2,208 delegates, over the 1,975 delegates needed to clinch the nomination.
