Warrants were served late Tuesday on the Detroit-area offices of three Japanese parts suppliers: Denso International America, Yazaki North America and Tokai Rika, also known as Tram, the Federal Bureau of Investigation said.

"This is not related to the investigation into Toyota recalls," Denso spokeswoman Bridgette LaRose Gollinger told AFP.

The Detroit-area headquarters of Denso's US subsidiary was "inspected" by the FBI and the US Justice Department "in regard to US antitrust laws," Gollinger wrote in an e-mail.

Denso "is cooperating with this investigation," Gollinger said, adding "we cannot comment on information related to the inspection."

OK.. hmm  perhaps we take a look at the facts..  Toyota has fought the UAW tooth and nail while developing its manufacturing structure here..  Two of the big three were failing as a result of the unions and poor management(capitulation with the unions) and government bought and paid for by the unions (Democrats..).. The government steps in and "saves" the carmakers from bankruptcy, with the end result of the unions owning a significant share of those two, and the "federal government owning the other parts, and then Toyota's unfortunate defects turn up....
