Federal prosecutors say they fear backers of Nevada rancher Cliven Bundy would use names and information that could be disclosed in a case over a 2014 armed standoff to target court officials and intimidate witnesses.
In court filings in Las Vegas, the government says prosecutors and the court have already received threats, including one recent Facebook post appearing to invite a "lone wolf attack."
That's got prosecutors seeking a court order to keep evidence they share with defendants confidential.
Their lawyer says the public has to be able to assess what crosses the line from criticism to illegal threats.
