NAACP President Derrick Johnson is slamming Trump's phone call with Georgia Secretary of State Brad Raffensperger and, in a new statement Monday, calls on the Fulton County District Attorney to investigate any state law violations committed by Trump after he "pressured" Raffensperger to recalculate votes in his favor.

"This is a racist attack on Black voters. President Trump's desperate and futile attempts to invalidate and falsify votes cast by Georgia voters add to a growing list of criminal acts that must be addressed," Johnson said in a statement.

Trump, in an hour-long phone call with Raffensperger on Saturday, falsely claimed it was "not possible" for him to have lost in The Peach State, and asked the secretary to "find" the exact number of votes he would need -- just one vote over the margin that he trailed Biden by -- so he could be declared the winner of an election that three separate counts confirmed he lost.

Fulton County District Attorney Fani Willis, in statement earlier Monday, did not rule out the possibility of filing state charges against Trump or his aides involved in the call, saying that it is her understanding Raffensperger's Elections Division has been requested to investigate the call and that, upon the conclusion of their investigation, the matter can be referred to both her office and the state's attorney general Chris Carr for potential charges.

Biden is headed to Georgia on Monday afternoon where the Senate's balance of power -- and the president-elect's subsequent hopes to pass the big ticket legislation he campaigned on -- hangs on a pair of Senate runoff elections.

The Georgia races have drawn national attention with both parties mobilizing their supporters ahead of the Jan. 5 election date. While Biden stumps in Atlanta Monday for Democratic contenders Rev. Raphael Warnock and Jon Ossoff, Trump headlines an evening rally in Dalton for sitting GOP Sens. Kelly Loeffler and David Perdue.

If Democrats win both races, the partisan make-up of the Senate will be 50-50, including the independents who caucus with Democrats, and Vice President Kamala Harris would serve as the tie-breaking vote in the Congress' upper chamber.

More than 3 million Georgians voted early in the races -- a record for statewide runoff elections in the Peach State.

Vice President Mike Pence, stumping for GOP Georgia senators on the eve of runoff elections there, vowed Republicans will have "our day in Congress" to contest the Electoral College results while urging supporters to put their immediate focus on defending the party's majority in the Senate.

"I know we’ve all got our doubts about the last election," Pence told hundreds of mostly maskless supporters inside a church in Milner, Georgia. "And I want to assure you I share the concerns of millions of Americans about voting irregularities. And I promise you, come this Wednesday, we’ll have our day in Congress. We’ll hear the objections. We’ll hear the evidence. But tomorrow it’s Georgia’s day."

Recent polls show tight races between sitting GOP Sens. David Perdue and Kelly Loeffler and Democratic contenders Jon Ossoff and Rev. Raphael Warnock -- forcing star power to the Peach State on the eve of the election including visits from Trump and Biden later on Monday.

Fulton County District Attorney Fani Willis in a statement Monday does not rule out the possibility of filing state charges against President Trump or his aides involved in the Saturday phone call where Trump pressured Georgia Secretary of State Brad Raffensperger to "find" votes to help him overturn the state's election. 

Willis said in the statement that it is her understanding Raffensperger's Elections Division has been requested to investigate the call and that upon the conclusion of their investigation the matter can be referred to both her office and the state's Attorney General Chris Carr for potential charges.

"Like many Americans, I have found the news reports about the President’s telephone call with the Georgia Secretary of State disturbing. It is my understanding from news reports that a member of the State Election Board has requested that the Secretary’s Elections Division investigate the call, after which the Board can refer the case to my office and the state Attorney General," she said in the statement.

"As I promised Fulton County voters last year, as District Attorney, I will enforce the law without fear or favor. Anyone who commits a felony violation of Georgia law in my jurisdiction will be held accountable. Once the investigation is complete, this matter, like all matters, will be handled by our office based on the facts and the law," she continued.

Willis' statement follows Raffensperger's telling ABC's "Good Morning America" Monday morning that he believed the Fulton County district attorney's office could be the most appropriate venue to investigate whether Trump and others on the call may have broken the law given potential conflict of interest concerns within his own office.
