PORTLAND, Ore. -- Cliven Bundy, the father of Ammon Bundy, was accused by the federal government Thursday of six crimes related to a 2014 protest at his Nevada ranch.

Cliven Bundy appeared in court Thursday afternoon. He will stay in jail until his next court hearing on Feb. 17.

Bundy will be behind bars in the same jail housing his sons, the leaders of an armed group that occupied an Oregon wildlife refuge. The elder Bundy was arrested Wednesday night when he arrived in Portland from Las Vegas to visit sons Ammon and Ryan Bundy.

Cliven Bundy was charged with leading a tense 2014 armed standoff with federal officials near his ranch in Nevada.

At his first court appearance, he asked for a court-appointed attorney. U.S. Magistrate Judge Janice Stewart said she wanted to see financial documents first.

Bundy was accused of conspiracy to commit an offense against the United States; assault on a federal officer by uses of deadly and dangerous weapon; use and carry of a firearm in relation to a crime of violence; interference with commerce by extortion; use and carry of a firearm in relation to a crime of violence, and obstruction of the administration of justice.

The 32-page criminal complaint accuses Bundy of leading more than 200 self-styled militia supporters into the April 2014 confrontation that had snipers with military-style weapons on a freeway overpass training their sights on federal agents who were attempting to enforce a court order to round up Bundy cattle.

"Bundy and his confederates recruited, organized and led hundreds of others in using armed force against law enforcement officers in order to achieve their criminal objectives," the charging document said.

The complaint refers to at least four other people as co-conspirators, but doesn't name them. Federal authorities said no other arrests were immediately expected.

U.S. Attorney Daniel Bogden said the matter remained under investigation.

The Malheur trip was posted on the Bundy Ranch's official Facebook page Wednesday evening, explaining that Bundy would be heading to Burns. The FBI announced his arrest Wednesday night.

The announcement was made amid news that the FBI had surrounded the four remaining armed occupiers at the refuge near Burns. The occupiers surrendered Thursday morning.

Bundy flew into Portland International Airport Wednesday night, where he was detained by the FBI and booked into the jail at 10:54 p.m.

Cliven's arrest comes more than two weeks after Ammon and Ryan Bundy were brought into custody.
