The allegations of election fraud that President Trump made are angering many of his loyal supporters, potentially unpredictable.

Although most of the lawsuits filed by Trump's campaign in battle states to reverse the election results have been dismissed, the US President has continuously attacked the election process.

Supporters of President Trump, some armed, gathered outside the home of the Michigan State Secretary-General on the night of December 6.

Georgia election officials, mostly Republicans, have said they have received threats of violence.

"They posted pictures of my house on Twitter," said Ann Jacobs, president of the Wisconsin Election Commission.

President Trump himself has contacted many Republican officials in the states, pressing them to help him reverse election results.

"If such actions are normalized, they create lasting consequences," tweeted Jeff Flake, a former Arizona Republican MP.

Last week, Gabriel Sterling, a top election official in Georgia, pleaded with President Trump to stop attacking the state election process on the grounds that his actions put them at risk.

The enthusiasm of loyal supporters has intensified as President Trump's electoral challenge-defying efforts have proven unlikely to succeed.

"They are getting more and more angry. We receive threatening emails all the time, day and night," said Pennsylvania Democratic Rep. Jennifer O'Mara.

Michigan Secretary-General Jocelyn Benson said she had just finished decorating a Christmas tree with her 4-year-old son when she heard screams from Trump supporters outside her own home.

Some shouted "Stop Stealing" and demanded that the results of Michigan be checked.

"From the first time the President tweeted about me and every time false information spread, the threat increased," Benson said in an interview on December 8.

"The only way out of this challenge, this split moment, is that elected officials in both parties have to condemn what's going on," she stressed.

Malcolm Kenyatta, the Pennsylvania Democratic Congressman, said she receives dozens of emails a day.

Michigan Democratic Rep. Darrin Camilleri received an email warning him to "prepare for the last meal".

Even Senator Camilleri's parents received threatening and defamatory calls.
