President Donald Trump asserted on Tuesday that Vice President Mike Pence has the power to reject electors that were fraudulently chosen.

“The Vice President has the power to reject fraudulently chosen electors,” Trump wrote on Tuesday in a tweet.

“I know we all have got our doubts about the last election,” Pence told a crowd of supporters in Georgia on Monday, adding that “I want to assure you that I share the concerns of millions of Americans about voting irregularities. I promise you, come this Wednesday, we will have our day in Congress.”

On Wednesday, Pence will preside over a joint session of Congress where Republican lawmakers argue he can choose to select an alternate slate of electors in favor of President Trump.

So far, 12 Republican senators and 140 GOP House members plan to object the election results with the President calling on Pence during his rally in Georgia Monday to select Republican electors.

Hours after Pence spoke, Trump told Georgia voters: “I hope Mike Pence comes through for us, I have to tell you.”

“I hope that our great vice president, our great vice president, comes through for us. He’s a great guy,” Trump said, without elaborating. “Of course, if he doesn’t come through, I won’t like him as much.”

But questions have arisen as to what power Pence actually has, as many legal experts have stated, the Vice-President mainly serves in ceremonial capacity.

For the last few weeks since the Nov. 3 election, Trump and his team have claimed that there has been electoral fraud, irregularities, and unconstitutional changes to the rules on mail-in voting in key states. On Dec. 14, when the Electoral College voted, Republican-backed voters also cast their votes for Trump and Pence in an effort to keep Trump’s legal challenges open.
