Donald Trump appears to be fixated on pushing his "Big Lie" of election fraud.

At a Saturday rally at the Iowa State Fair, Trump bragged about refusing to concede, complained about the Supreme Court not overturning the election, and revealed that he pushes the conspiracy theory because of the applause it receives.

"Mitch McConnell said we have to get back to business. Mitch McConnell should have challenged that election," Trump said, even though he lost.

Trump went on to allege that Senate Democratic Leader Chuck Schumer would have challenged the election.

"We had plenty of material to challenge the election. He should have challenged the election. Schumer would have challenged the election."

"Mitch McConnell did not have the courage to challenge the election. He is only a leader because he raises a lot of money and gives it to senators, that is his only form of leadership," Trump said. "He should have challenged the election."
