Board recommends dismissal of anti-Obama Marine By Michael Pearson and Moni Basu, CNN April 6, 2012 -- Updated 1425 GMT (2225 HKT) Sgt. Gary Stein is facing discharge from the Marines due to comments he made about President Obama. Marine Sgt. Gary Stein posted anti-Obama comments on his Facebook page A board recommends an "other than honorable" discharge A separation authority will make the final decision Stein said he was entitled to his opinions and alleged a PR campaign against him (CNN) -- A Marine Corps board has recommended that a politically active Marine sergeant who questioned President Barack Obama's authority be dismissed from service with an "other than honorable" discharge. Sgt. Gary Stein, who posted anti-Obama comments on his Facebook page, stands accused of violating a catch-all military justice provision against conduct endangering "good order and discipline." He is also accused of violating a Department of Defense policy limiting the political activities of service members. The recommendation for dismissal, made late Thursday, will now go to a separation authority headed by Brig. Gen. Daniel Yoo, commander of the Marine Corps Recruit Depot in San Diego, said Maj. Michael Armistead, the public affairs director for the installation. It could take two to three weeks for the authority to hand down a decision, Armistead said. If he leaves the Marines with an other than honorable discharge, Stein will be demoted a rank to lance corporal, Armistead said. Stein came under scrutiny from Marine officials after saying he would not obey Obama's orders. In a January 26 post to the Armed Forces Tea Party Facebook page, Stein called Obama a liar. Two days later, he said the president is "the 'Domestic Enemy' our oath speaks about." In a March 4 posting, he questioned Obama's birth certificate. Another discussion on the site in March said he would refuse to obey orders given by Obama. He later clarified to say he meant illegal orders, which he has explained as orders such as sending the military to Syria without congressional approval. "The allegations drummed up against me are no more than an agenda by the Marine Corps to use me as an example," Stein said in a statement posted to his page. If I am guilty of anything it would be that I am American, a freedom loving Conservative, hell bent on defending the constitution and preserving Americas greatness. He noted that the opinions he expressed were his own, saying, "I have never spoken on behalf of the Marine Corps or in uniform." He told CNN the charges were a "PR thing." "They have to make some sort of stand with this," he said. On Friday, his Facebook page said simply: "On to the next fight." CNN's Chelsea J. Carter and Barbara Starr contributed to this report.
