(CNN) A woman suspected of sending a letter containing the poison ricin to President Donald Trump was arrested as she tried to enter the US from Canada at a border crossing in New York state, a US law enforcement official said. The woman was carrying a gun and arrested by US authorities, according to the law enforcement official. US prosecutors in Washington, DC, are expected to bring charges against her. CNN previously reported that law enforcement had intercepted a ricin package sent to Trump last week, according to two law enforcement officials, and that investigators were looking into the possibility that it came from Canada. A person familiar with the investigation told CNN's Josh Campbell the letter was mailed from St. Hubert, Quebec, and contained a granular substance with similar physical characteristics to ground castor beans.
