Report: Cliven Bundy supporters investigated by FBI

The FBI is investigating supporters of Nevada rancher Cliven Bundy after an April 12 showdown with the Bureau of Land Management, reports CBS affiliate KLAS.

Bundy, who has come under fire for racist remarks - including saying that black Americans might have been better off as slaves - has been in a dispute with the land agency over whether his cattle can graze for free on federal land. On April 12, he and several hundred supporters - some armed - confronted agents from the BLM attempting to round up his cattle, and managed to get them to back down. Metro police officers were on the scene about 75 miles northeast of Las Vegas to act as a buffer between Bundy's group and federal agents.

Now, according to the station, the FBI is investigating alleged death threats, intimidation and weapons violations during the showdown. Metro officers told KLAS members of the so-called militia that assembled to challenge the round-up of Bundy's cattle taunted them, pointed guns at them and said they should be ready to die.

The Clark County Sheriff's Department confirmed to CBS News' Crimesider that some of their officials have been interviewed by the FBI. Calls to the Las Vegas division of the FBI were not immediately returned.
