President Donald Trump thanked the millions of voters who supported him but suggested that “a very sad group of people” is trying to steal the presidential election in an early Wednesday speech.

“Millions and millions of people voted for us tonight. And a very sad group of people is trying to disenfranchise that group of people, and we won’t stand for it,” the president said.

“This is a fraud on the American public. This is an embarrassment to our country. We were getting ready to win this election. Frankly, we did win this election. So our goal now is to ensure the integrity,” the president continued.

President Trump then vowed to bring the case to the Supreme Court.

“We’ll be going to the U.S. Supreme Court. We want all voting to stop. We don’t want them to find any ballots at 4 o’clock in the morning and add them to the list, OK? he added. “We will win this, and as far as I’m concerned, we already have.”

Philadelphia has stopped counting mail-in ballots for the night, raising questions on election integrity. Of some 350,000 mail-in ballots received, only 76,000 have been counted, according to the New York Post. 

“Pausing vote-counting is suspicious. Very suspicious,” former acting Director of the U.S. National Intelligence Richard Grenell tweeted. “Pull an all-nighter. Get it together.”

“I’m 69. I’ve never seen states just stop counting votes on election night,” one Twitter user wrote.

“President Trump wants the votes counted. Democratic cities literally stopped counting the votes. That’s where we are,” Committee to Unleash Prosperity President Phil Kerpen tweeted.

In some states, mail-in ballots will be tallied even if they are received days after Election Day. The state Supreme Court in Pennsylvania allowed ballots to arrive at election offices by Friday night, even without a legible postmark or other proof of mailing. 

President Trump’s victory in Texas and Florida slashed the Democratic dream of flipping Texas and debunked many polls showing Democratic presidential nominee Joe Biden’s double-digit leads.
