2024 election updates: Trump delivers remarks in Georgia | WATCH

More than 250,000 voters cast ballots during the first two days of in-person statewide early voting in the swing state, and over 1.5 million Michigan voters have submitted absentee ballots, Michigan Secretary of State Jocelyn Benson announced at a press conference on Monday.

Benson said that 24% of the state's active registered voters have by now already cast their ballot.

Benson also highlighted some demographic breakdowns about who has voted early in Michigan so far. Almost two-thirds of Michigan citizens who voted by mail are older than 60, but 61% of those who early voted so far are under 60, and 13.5% of early voters are under 30. Benson added that "of all the votes cast to date in Michigan's elections, 55% are from women and 44% are from men."

President Joe Biden has cast an early ballot in the 2024 general election.

It's a bittersweet moment for Biden, who decided to end his reelection campaign in July because of growing concerns about his health and Democrats' worries about his chances of defeating former President Donald Trump. Biden voted on Monday at the state of Delaware Department of Elections, not far from his home outside Wilmington, Delaware at an early voting site, where voters were lined up down the street to cast ballots.

President Joe Biden is at a polling place in New Castle, Delaware, to vote early in the 2024 election.

According to reporters traveling with the president, there was a line of more than 100 people when he arrived. Biden walked toward the back of the line and was seen greeting and speaking with voters.

Harris criticized Trump's rally at Madison Square Garden, saying the former president is "fixated on his grievances, on himself and on dividing our country."

"It is absolutely something that is intended to and is fanning the fuel of trying to divide our country. And as I've said many times, I'll say tomorrow night in my speech, there's a big difference between he and I," Harris told reporters as she departed Joint Base Andrews for a day of campaigning in Michigan.

Asked to respond to the comments about Puerto Rico at the rally, which the Trump campaign has tried to distance itself from, Harris pointed to her support for Puerto Rico as a senator and her "opportunity economy" proposal.

"I'm very proud to have the support of folks like Bad Bunny and Jennifer Lopez and others who were supporting me before that nonsense last night at Madison Square Garden, and are supporting me because they understand that they want a president of the United States that's about uplifting the people and not berating, not calling America a garbage can, which is what Donald Trump, those are the words he has used."
