Denise Helms' Facebook page was protected by privacy settings, the Modesto (Calif.) Bee reported. But one of her Facebook friends picked up the comment made after Obama won re-election Tuesday and broadcast it via Twitter.
Her take on the election was: "Maybe he will get assassinated this term..!!"
Local news media picked up the story and it spread across the country. By Wednesday, she told her employer, a Cold Stone Creamery outlet in Turlock, Calif., she had received death threats -- and 24 hours later she was out of a job.
Duane Costa, the store's owner, described Helms' Facebook message as "disgusting" but said Helms had never used similar language at work.
"I had to take everything into consideration -- her welfare at work and that of the other workers," he said. "I can't have a hostile work environment. I had other employees who were afraid to come to work."
Helms could be in even worse trouble. The New York Daily News said the Secret Service is investigating her for a potential crime -- threatening the life of the president.
