Customs and Border Protection officers in upstate New York arrested a woman attempting to enter the United States from Canada who is believed to have sent a letter containing the poison ricin to the White House last week.
The woman was taken into custody by federal law enforcement in Buffalo, New York, a federal official told CNN. She was carrying a gun when federal officers detained her. The woman, whose name and country of origin have not been released, is expected to face federal charges brought by prosecutors in Washington, D.C., for allegedly mailing the letter to President Trump. CBP did not immediately respond to a request for comment.
