JAKE Tapper called Donald Trump a "grotesque, dangerous and un-American" for sharing his "rigged election" claims.
The CNN host made the stinging remarks on Tuesday after Trump made a baseless claim of "massive voter fraud in Georgia," a battleground state clinched by his Democratic rival Joe Biden.
Trapper wrote: "Grotesque, dangerous, undemocratic, un-American.
"Called out by a GOP official in Georgia for not condemning calls for violence against election officials, the president responds with the deranged conspiracy theories that are feeding the threats."
The outgoing president raged: "Rigged Election. Show signatures and envelopes.
"Expose the massive voter fraud in Georgia. What is Secretary of State and @BrianKempGA afraid of. They know what we’ll find!!!"
He was responding to a video shared by a WXIA journalists in which the state's Voting System Implementation Manager Gabriel Sterling tells reporters "it has all gone too far."
Sterling demanded Trump "stop inspiring people to commit potential acts of violence" after a noose was found outside an election worker's home and Georgia Secretary of State Brad Raffensperger received death threats.
Sterling confirmed his own wife received sexualized threats and he now needed police protection during the conference on Tuesday.
He said: "Someone is going to get hurt. Someone is going to get shot. Someone's going to get killed. And it's not right.
"I have police protection outside my house now, fine," Sterling said. "I took a higher-profile job. I get it. This kid took a job. He just took a job, and it's just wrong.
"I can't begin to explain the level of anger I have over this, and every American, every Georgian, Republican and Democrat alike, should have the same level of anger."
Reports indicate that election officials in many key states have had their lives threatened.
Arizona's Secretary of State Katie Hobbs said "abhorrent" escalating threats were made against her and her family on Parler, a social media platform favored by right-wing conservatives.

"I was prepared for these threats of violence and vitriol," Hobbs said in a statement. "I have been a social worker for many years and can anticipate this reaction when certain people feel powerless and angry.
"There are those, including the president, members of Congress and other elected officials, who are perpetuating misinformation and are encouraging others to distrust the election results in a manner that violates the oath of office they took.
"It is well past time that they stop. Their words and actions have consequences."
