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.

The United States Postal Inspection Service, the law-enforcement arm of the Postal Service, this month issued a bulletin to local, state and federal law-enforcement agencies around the country warning them to be mindful of threats to postal workers and the mail because of the controversy surrounding mail-in ballots for the Nov. 3 election.

“The intense media focus and public awareness surrounding these mail-in ballots could potentially make USPS employees and vehicle a tempting target for criminal activities,” the one-page Oct. 7 bulletin said. It goes on to list a series of possible threats including assaults of USPS personnel and general mail theft, among other concerns.

The bulletin comes as the president continues to sow doubt in the integrity of the mail-in ballot process.

When Sen. Kamala Harris, D-Calif., took part in an interview on a South Florida radio show called "Caribbean Riddims," she sprinkled the Jamaican phrase "ya mon" throughout the interview with a heavy hand.

The Democratic vice presidential nominee is the daughter of Jamaican and Indian immigrants and playing up her Jamaican heritage is a huge part of the Biden-Harris campaign's outreach to Afro-Caribbean voters in the Sunshine State.

The voting bloc is significant in Florida, especially in South Florida and along the critical I-4 corridor, a bellwether in this battleground state. According to the Migration Policy Institute, 41% of the nation's 4.4 million Caribbean immigrants live in Florida, and Miami-Dade County has the highest number of Caribbean immigrants in the U.S. with 862,000 Caribbean immigrants calling it home. If the campaign's outreach to this community is successful, it could help turn the state into an electoral victory for Biden and Harris.

Exactly two weeks from Election Day, President Trump delivered a shorter-than-normal speech at a packed rally in cold Erie, Pennsylvania, Tuesday night where he continued to downplay the pandemic despite surging cases around the country and claimed Joe Biden would bring "depression, doom and despair" if elected.

Trump, who remarked how cold it was (about 50 degrees and windy) multiple times throughout the night, spoke for only 57 minutes Tuesday night after holding back-to-back rallies in Arizona on Sunday. After spending the last few days raging at the press, Dr. Anthony Fauci (who was not mentioned), and calling for multiple opponents to be locked up -- the president's speech Tuesday night was tamer by Trump's standards.

The president blasted Pennsylvania Gov. Tom Wolf for keeping restrictions on the state amid the ongoing coronavirus pandemic and not fully opening up the economy, with Trump continuing to claim that the U.S. is "rounding the turn" and eager to return to "normal life."

"We're rounding the turn on the pandemic -- 56%, and it's a record. Epic job growth. Safe vaccines that quickly end the pandemic. It’s ending. Normal life -- that's all we want," he said. "You know what we want? Normal life. Normal life will finally resume, and next year will be the greatest economic year in the history of our country."

But the U.S. is far from "rounding the turn" with over 41 states seeing increases in COVID-19 cases and 42 seeing an increase in hospitalizations, according to The COVID Tracking Project. Trump tried using Florida as an example of a state that previously saw a spike, recovered and opened up their economy, but the state is now also seeing an increase in cases, positivity rate, hospitalizations and daily deaths.

"You know, Florida’s open. All these -- Florida had a surge, great governor, surge went down," Trump said. "Arizona had a surge, went down -- great governor. Texas had a surge, went down. You guys never opened. What the hell is going on in Pennsylvania, right?"

First lady Melania Trump, who had been scheduled to appear, ended up canceling due to a lingering cough.
