Ricin Letter Suspect Arrested

The woman suspected of sending a ricin-laced package to President Trump was arrested by US authorities at a New York border crossing, law enforcement sources tell the AP and CNN. The woman was allegedly trying to enter the US from Canada, and was carrying a gun. Prosecutors in Washington, DC, are expected to file federal charges against her. Authorities are also investigating similar packages sent to Texas; it's not yet clear whether the cases are related. (The package never made it to the White House.)
