Portland, Ore. • An Arizona man pleaded guilty to conspiracy for his role in the armed occupation of a national wildlife refuge in Oregon and was nearing a resolution to charges he faces from a 2014 standoff with federal agents at Cliven Bundy's Nevada ranch.

Blaine Cooper, 37, of Humboldt, Ariz., admitted to a federal judge in Portland on Thursday that he appeared in a video with occupation leader Ammon Bundy, urging patriots to show up at the refuge with firearms, The Oregonian/OregonLive reported.

"I could see how calling people out to a refuge armed could be intimidating," Cooper said.

Federal prosecutors had no evidence that Cooper carried a gun at the Malheur National Wildlife Refuge, but Assistant U.S. Attorney Craig Gabriel said the man was part of the first convoy of people to arrive there on Jan. 2, starting an occupation that lasted nearly six weeks.

The group had been in Burns, Ore., protesting the return to federal prison of two ranchers convicted of setting fires.

Court records show Cooper will be sentenced Nov. 18. He's expected to receive six months in prison, with credit for time served, and six months in a either a halfway house or home detention.

He's the seventh defendant to plead guilty in the case. Another 19, including Ammon Bundy, are awaiting trial.

Meanwhile, it was revealed in court that Cooper has reached a tentative deal in the Nevada case, likely pleading guilty to two charges.

Krista Shipsey, Cooper's defense lawyer, asked Cooper's co-defendants and others to respect his choice.

"It's incredibly hard for him to be here today," Shipsey said. "He felt he needed to take care of this, but I hope they respect this is what's best for him."

Cooper had wanted to resolve the cases for a long time, she said.

"He is very apologetic about his behavior," Shipsey said. "He felt like a nobody, and this movement gave him a purpose in his life...The fame took over his senses."
