An excerpt from Salon.com:

Speculation continues to run wild about President Bush's mystery bulge. Since Friday, when Salon first raised questions about the rectangular bulge that was visible under Bush's suit coat during the presidential debates, many observers in the press and on the Internet have wondered aloud whether the verbally and factually challenged president might be receiving coaching via a hidden electronic device.

Now a technical expert who designs and makes such devices for the U.S. military and private industry tells Salon that he believes the bulge is indeed a transceiver designed to receive electronic signals and transmit them to a hidden earpiece lodged in Bush's ear canal.

"There's no question about it. It's a pretty obvious one -- larger than most because it probably has descrambling capability," said Alex Darbut, technical and business development vice president for Resistance Technology in Arden Hills, Minn. Darbut examined photographs of the president's back taken from the Fox News video feed at the first presidential debate in Coral Gables, Fla., as well as 2002 photos of the president driving and working in a T-shirt on his Crawford ranch, which were posted on the White House Web site.
