President Donald Trump has warned that he will not forget the Republican senators, including Senate Majority Leader Mitch McConnell (R-Ky.), who have refused to stand with him in the battle against an apparently fraudulent election.

In a tweet on Christmas Eve, President Trump complained that a number of senators have done nothing to help him even though the president had helped lift them over the finish line since he entered the White House.

“I saved at least 8 Republican Senators, including Mitch, from losing in the last Rigged (for President) Election. Now they (almost all) sit back and watch me fight against a crooked and vicious foe, the Radical Left Democrats. I will NEVER FORGET!” President Trump wrote.

The president delivered the warning as he is seeking to seize on another method to contest the election, which would require Republicans to object to certifying the Electoral College’s vote. Congress is scheduled to meet in a joint session on Jan. 6 to count the electoral votes.

A few of Republicans, including Alabama Senator-elect Tommy Tuberville, have voiced their support for a potential challenge to the presidential election result, which was allegedly rigged in favor of Democrat Joe Biden.

Tuberville last week accused the Democrats of trying to steal the presidential election and suggested that he will reject Electoral College vote on the Senate floor in the Jan. 6 session.

However, McConnell—who was labelled as a “traitor to American Patriots” for acknowledging Biden’s victory in December, will reportedly reach out to Tuberville to urge him to abandon President Trump to avoid a so-called messy floor fight over finalizing the results of the Electoral College vote.

President Trump has called on Republicans not to give up too soon and they “must finally learn to fight” for an election that he has repeatedly claimed was stolen by Democrats after more than 74 million Americans voted for him—the largest number of votes for a sitting president.
