The Canadian woman charged with sending a ricin-laced letter to President Trump apparently tweeted a hashtag supportive of killing the commander-in-chief less than two weeks ago. Pascale Ferrier, of Quebec, was arrested Sunday at the border crossing between Fort Erie, Ontario, and Buffalo, New York, after allegedly mailing a letter addressed to Trump containing the highly toxic substance, according to CBC News. She was carrying a gun at the time of her arrest at the Peace Bridge crossing, CNN said.
