10 Times Celebrities Threatened the President With Violence
The only one on this list to go beyond words or artistic expression, actress Shannon Guess Richardson of Texas was known for having small roles in programs like The Walking Dead and The Vampire Diaries.
In 2014, Richardson was sentenced to 18 years in prison and forced to pay $367,000 after admitting that she sent letters containing ricin to then President Barack Obama and then New York Mayor Michael Bloomberg.
"The letters, which contained what the FBI described as 'very low concentrations' of ricin, were discovered before causing any injuries or fatalities," reported CNN.
"Richardson ... initially told FBI agents that her now-estranged husband had sent the tainted letters. But authorities said Richardson was found to be 'deceptive' in a polygraph exam."
