The would-be assassin of former President Trump was sentenced to 262 months in prison.

On Thursday, Pascale Cecile Veronique Ferrier, a 56-year-old dual citizen of Canada and France, was selected to nearly 22 years in prison for mailing a letter containing the poison ricin in 2020 to then-President Trump and others. She pleaded guilty in January to violating biological weapons prohibitions.

In the letter, Ferrier referred to Trump as “The Ugly Tyrant Clown” and laced it with the potentially deadly ricin, saying, “If it doesn’t work, I’ll find better recipe for another poison, or I might use my gun when I’ll be able to come. Enjoy! FREE REBEL SPIRIT.”

Authorities arrested Ferrier while attempting to drive across the U.S.-Canada border while carrying a gun, a knife, and hundreds of rounds of ammunition, authorities said. The letter was intercepted at a mail sorting facility in September 2020, before it could reach the White House.

In September 2020, Ferrier posted on X, then called Twitter, that someone should “please shoot [T]rump in the face.”

Ferrier told the judge that she considers herself a “peaceful and genuinely kind person” but admitted she gets angry about problems like unfairness, abuses of power and “stupid rules.” She also said she considers herself to be an “activist” rather than a “terrorist.”

U.S. District Judge Dabney Friedrich handed down the 262-month sentence outlined in a plea agreement with prosecutors, which also would expel Ferrier from the U.S. once she is released from prison. She will be required to be under supervised release for life, if she ever returns.

Prosecutor Michael Friedman called the sentence an “appropriately harsh punishment” that sends a clear message.

“There is absolutely no place for politically motivated violence in the United States of America,” he said. “There is no excuse for threatening public officials or targeting our public servants.”
