Top Republican leaders haven't acknowledged President-elect Joe Biden's victory, with no customary words of congratulations from Senate Majority Leader Mitch McConnell.
A small group of Republicans have called for the country to accept the results and move on.
Sen. Mitt Romney said yesterday it was "appropriate" for President Trump to ask for recounts and challenge the results. But he also said there has been no evidence so far of any widespread fraud.
Other lawmakers, like Sen. Lindsey Graham, say there are plenty of allegations to look in to.
"[If] Republicans don't challenge and change the U.S. election system, there'll never be another Republican president elected again. President Trump should not concede," Graham said.
