Election 2020 updates: Trump delivers shorter speech in chilly Pennsylvania

As early voting officially kicks off in Wisconsin, the state has already seen about four times more absentee ballots cast and five times as many ballots requested as compared with this time last year -- and the start of early in-person voting today is likely to bring in another big wave of voters.

Early voting schedules are different in every municipality, but it runs from today through Oct. 30. It's technically early absentee in-person: Voters receive an absentee ballot in their clerks' office, fill it out and hand it back to the clerks.

This morning, just before early in-person voting began, over 1.4 million ballots had been requested and 915,965 returned.

Some voters in Milwaukee queued up in long lines waiting to enter their polling sites.

A photo is circulating on Twitter depicting a City of Miami police officer wearing a pro-Trump mask inside a polling site. The chair of the Miami-Dade Democratic Party, Steve Simeonidis, took the photo and posted it but ABC News could not confirm the officer's name.

Miami Police issued a statement referencing "the photograph being circulated," noting that "this behavior is unacceptable, a violation of departmental policy, and is being addressed immediately." A public information officer with the department, Mike Vega, told ABC News by phone that the chief of police will take "immediate action." 

Vega said that donning political clothing or accessories is "a violation of our departmental orders," and Simeonidis told the Miami Herald he considered the officer's behavior "voter intimidation."

A spokeswoman for the Miami-Dade County elections office told ABC News that a complaint about the incident was brought to her attention this morning. She then passed it on to Miami Police.

Michigan Secretary of State Jocelyn Benson is estimating record turnout in this year's election, as more than 3 million Michigan voters have requested their ballots and over half of those voters have already returned them -- surpassing expectations with still two weeks until Nov. 3.

Looking ahead to the next two weeks, Benson told reporters Tuesday morning she is cautioning voters against using the mail due to potential postal delays, instead encouraging them to rely on drop boxes and hand delivering ballots to clerks offices to ensure their ballots meet the Election Day deadline.

There is currently a legal dispute in Michigan over the deadline for accepting mail ballots, with the Michigan Court of Appeals late last week blocking a lower court's order that extended the deadline for absentee ballots to arrive by two weeks.

First lady Melania Trump is no longer traveling with the president to Pennsylvania Tuesday, with her office citing a "lingering cough." 

"Mrs. Trump continues to feel better every day following her recovery from COVID-19, but with a lingering cough, and out of an abundance of caution, she will not be traveling today," the first lady's chief of staff and spokesperson Stephanie Grisham said in a statement. 

Tuesday's campaign visit to Pennsylvania was supposed to have been the first lady's first public appearance after contracting COVID-19.

Tuesday's event would have been the first lady's first rally appearance in over a year. She last joined Trump on stage at his reelection kickoff in Orlando in June 2019.
