TEXARKANA, Texas (AP) A U.S. judge says a woman accused of sending ricin-laced letters to President Barack Obama and New York Mayor Michael Bloomberg is competent to stand trial.
The judge said Wednesday that Shannon Guess Richardson is mentally competent.
Richardson is accused of sending the letters to Obama, Bloomberg and a man who heads Bloomberg's national gun control organization.
Richardson pleaded not guilty Wednesday to two counts of mailing a threatening communication and one count of making a threat against the president of the United States.
A federal affidavit alleges Richardson called authorities to implicate her husband before she was arrested in June.
