President Donald Trump once again went on the attack Tuesday, questioning the US voting process just before setting off to host rallies in three states.

Trump told reporters it would be inappropriate to take extra time to count the tens of millions of ballots cast by mail in his race against Democrat Joe Biden.

It would be very, very proper and very nice if a winner words he planned on November 3rd instead of counting ballots for two weeks, which is totally inappropriate, and I don't believe that that's by our laws, experts say.

It could take days or weeks to tally million's of mail in ballots, meaning a winner might not be declared the night of November 3rd when polls close.

Trump has repeatedly without evidence suggested that an increase in mail in voting will lead to an increase in fraud, though election experts say that is rare in U.

S elections.

Trump then set off for Michigan, Wisconsin and Nebraska beginning in Lansing, where he mocked former President Barack Obama's earlier stump speech Tuesday.

But there's never been anything like this in terms of enthusiasm in terms of crowds.

I saw Obama this morning, he had a couple of cars there honking their horns.

Our current president, he winds that 60 minutes is too tough.

Obama was back on the campaign trail in Orlando, Florida, and pulled no punches.

Covert Covert covert.

He's complaining.

He's jealous of Covitz media coverage.

Meanwhile, Biden headed to traditional Republican territory, visiting Georgia, which has not supported a Democrat in a U.

S presidential election since 1992.

As the heart of this nation turn to stone, I don't think so.

Refused to believe it.

I know this country.

I know our people.

I know we can unite and heal this nation.

Voters also heard from first lady Melania Trump in Pennsylvania.

I do not always agree what the way he say's things, but it is important to him that he speaks directly to the people he serves.

Democrats are voting early in greater numbers than Republicans this year, but some states do not allow officials to even begin counting ballots until the polls close on Election day.
