TRENTON (AP)  A New Jersey blogger about to stand trial on charges that he made death threats against federal judges was apparently paid by the F.B.I. in its battle against domestic terrorism, according to a published report.

The blogger, Hal Turner, received thousands of dollars from the Federal Bureau of Investigation to report on neo-Nazis and white supremacist groups and was sent undercover to Brazil, according to a report on Sunday by The Record of Bergen County.

Mr. Turner also claims the F.B.I. coached him to make racist, anti-Semitic and other threatening statements on his Internet radio show, but the newspaper also found that many federal officials were concerned that his audience might follow up on his violent speech.

The newspaper reviewed numerous government documents, e-mail messages, court records and almost 20 hours of jailhouse interviews with Turner.
