Before embarking on a packed day of campaign rallies, President Trump stopped at a library in Florida's Palm Beach County on Saturday to cast his ballot.

"I voted for a guy named Trump," he told reporters.

While the president has voted by mail in the past, in recent months he has decried the integrity of voting by mail, falsely asserting that it results in rampant fraud.

"It was a very secure vote, much more secure than when you send in a ballot," Trump said on Saturday, without evidence.

While many have states rushed to expand voting by mail this spring due to the pandemic, Democrats have started encouraging voters to cast ballots early and in person, if possible, as the prospect of delayed tabulations and postal service slowdowns loom.

More than 50 million people have already voted in the election either by mail or in person, according to the U.S. Elections Project, a turnout-tracking database run by University of Florida political scientist Michael McDonald.

Trump's running mate, Vice President Mike Pence, voted early on Friday in Indianapolis.

After voting, President Trump was scheduled to depart Florida for rallies Saturday in North Carolina and Ohio. The president will also hold a rally in Wisconsin, which is currently experiencing one of the worst coronavirus outbreaks in the country.

Trump told reporters that the rallies will be "big ones," and boasted about the crowds he's been attracting.

His Democratic opponent, Joe Biden, is holding a pair of rallies in Pennsylvania on Saturday, including a drive-in rally in Luzerne County with Jon Bon Jovi.
