ATLANTA, Ga. (AP) President-elect Joe Biden on Monday told Georgia Democrats they had the power to chart the course for a generation as President Donald Trump urged Republican voters to swamp the polls ahead of runoff elections that will determine control of the U.S. Senate .

Trump made his final-hours pitch to voters at a nighttime rally in north Georgia, where Republicans were banking on strong voter turnout Tuesday to reelect Sen. Kelly Loeffler and David Perdue and hold control of the chamber.

Biden campaigned with Democrats Jon Ossoff and Raphael Warnock in Atlanta, hoping he could recreate the coalition that secured him a narrow victory in the presidential race in November.

Folks, this is it. This is it. Its a new year, and tomorrow can be a new day for Atlanta, for Georgia and for America, Biden said at a drive-in rally. Unlike any time in my career, one state one state can chart the course, not just for the four years but for the next generation.

The stakes have drawn hundreds of millions of dollars in campaign spending to a once solidly Republican state that now finds itself as the nations premier battleground. Biden won Georgias 16 electoral votes by about 12,000 votes out of 5 million cast in November, though Trump continues pushing false assertions of widespread fraud that even his now-former attorney general and Georgias Republican secretary of state along with a litany of state and federal judges have said did not happen.

The presidents trip came a day after disclosure of a remarkable telephone call he made to the Georgia secretary of state over the weekend. Trump pressured Republican Brad Raffensperger to find enough votes to overturn Georgias election results ahead of Wednesdays joint session of Congress that will certify Bidens Electoral College victory. The call highlighted how Trump has used the Georgia campaign to make clear his continued hold on Republican politics.

Angry after the Raffensperger call, Trump floated the idea of pulling out of the rally but was persuaded to go ahead with it so he would have a chance to reiterate his claims of election fraud. Republicans were wary as to whether Trump would focus only on himself and fail to promote the two GOP candidates.

A top Georgia election official said hours before Trumps rally that he wanted to scream after hearing audio of the presidents call with Raffensperger.

Do not self-suppress your own vote, said Gabriel Sterling, Georgias voting system implementation manager.

But Trump, at the rally in Dalton, Georgia, spent much of his address on message, making an impassioned case that Loefflers and Perdues races were among the most important Georgia voters would ever face and made the case that the fate of our country is at stake.

To be sure, he also spent a fair amount of time rehashing false claims that the November election was rigged. He fumed that Republican Gov. Brian Kemp was incompetent and replayed many of the same debunked claims that he raised days ago in his call with Raffensperger.

The Democrats are trying to steal the White House, you cannot let them, Trump said. You just cant let them steal the U.S. Senate, you cant let it happen.

Biden on Monday took aim at Trumps scheme by declaring that politicians cannot assert, take or seize power by undermining legitimate elections.

Biden said he needs a Senate majority to pass legislation to combat the coronavirus, and he blasted Perdue and Loeffler as obstructionist Trump loyalists. Loeffler says she will join other Republican lawmakers in objecting to the Electoral College certification of Bidens victory by Congress on Wednesday.

You have two senators who think theyve sworn an oath to Donald Trump, not the United States Constitution, Biden said.
