PORTLAND, Ore. — Nevada rancher Cliven Bundy must stay behind bars, a federal judge ruled Tuesday, calling him a danger to the community after he arrived in Oregon to support the armed occupation of a national wildlife preserve led by his sons.

U.S. Magistrate Judge Janice Stewart also said Bundy should not be released ahead of trial because there is a risk he won't show up for future court dates. Federal prosecutors called the 69-year-old "lawless and violent" in a document filed before the hearing, an assertion his attorney and family denied.

"If he is released and he goes back to his ranch, that is likely the last the government will see of him," Stewart said.
