Former President Donald Trump has long had a contentious relationship with Senate Republican Leader Mitch McConnell (R-KY), who many of Trump's supporters would like to see removed from his current leadership position.

During a campaign rally in the final days ahead of Tuesday's election, Trump joked about the likely "painful" endorsement he'd received earlier in the year from McConnell and further suggested that it was time to "get rid of" the elderly senator, according to The Hill.

The reason Trump cited for why he and others would like to see McConnell's resignation from power -- aside from his prior open opposition to the GOP nominee -- was the Republican senator's friendly relationship with President Joe Biden and the assistance he provided the Democrat in getting parts of his agenda passed through the closely split Senate.

McConnell endorsed Trump in March

It was in March, according to the Associated Press at the time, that Sen. McConnell issued a tepid endorsement of former President Trump after it became clear that he would once again be the Republican Party's presidential nominee.

The outlet noted that McConnell, who blamed Trump for the "disgraceful" Jan. 6 Capitol riot of 2021, had not spoken to the former president since the aftermath of the 2020 election, when he congratulated President Biden on his apparent victory while Trump was still challenging the disputed electoral results.

In a terse statement, McConnell said, "It is abundantly clear that former President Trump has earned the requisite support of Republican voters to be our nominee for President of the United States."

"It should come as no surprise that as nominee, he will have my support," the senator added.

Trump says it is time to "get rid of" McConnell

At the time, per the AP, former President Trump expressed his appreciation for Sen. McConnell's endorsement and said in a social media post, "Thank you, Mitch. I look forward to working with you and a Republican Senate MAJORITY to MAKE AMERICA GREAT AGAIN!"

Yet, it is unclear what, if any, support McConnell provided to Trump's re-election effort beyond the endorsement, and Trump seemed to indicate at a campaign rally over the weekend that he was looking beyond the Senate Republican Leader in terms of who he would work with if he regained the White House.

At a North Carolina rally on Sunday, Trump accused McConnell of aiding the Biden-Harris administration and said, per The Hill, "They caused inflation. They screwed up my energy policy, and the prices went way up and everything else, real simple. In addition to that, they way overspent. They got trillions and trillions of dollars."

"Hopefully we get rid of Mitch McConnell pretty soon, because he helped them," he added, according to Mediaite, then joked to the crowd, "Can you believe he endorsed me? Boy, that must have been a painful day in his life."

McConnell won't be the Senate leader next year

Now that the former president is once again the president-elect, Trump likely won't have to worry too much about having to work with Sen. McConnell even though the Kentucky Republican has not resigned and continues to serve out his current term.

That is because, according to the AP, McConnell announced his plans to step down from his leadership role and hand over the reigns of the Senate to a younger colleague in the next congressional session that will begin in January.

Whether the apparent incoming Republican Senate majority, based on Tuesday night's election results, will work with Trump on his MAGA agenda or prove to be as much of a stumbling block as the Democrats is something that remains to be seen.
