Man pleads guilty in Obama anthrax hoax

DENVER -- A man from the Denver area has pleaded guilty to sending letters containing white powder to President Barack Obama, members of Congress from Colorado and Alabama, and to Argentine consulates.

Jay DeVaughn pleaded guilty Thursday to 13 federal counts of mailing threatening communications. DeVaughn, also known as Jay Paige Ewards, mailed a letter to Obama that was intercepted Sept. 10, 2009.

The white powder in the letters was harmless.

The 40-year-old DeVaughn mailed letters criticizing the federal health care reform to members of Colorado's congressional delegation last year and this year. He sent letters to Alabama congressional members in January.

He will be sentenced Nov. 19, when he will face about two years to nearly five years in prison.
