Washington ( CNN ) -- A Marine who used his Facebook page to criticize President Barack Obama has been discharged , a Marine Corps spokesman said Wednesday . Sgt . Gary Stein was given an `` other-than-honorable '' discharge , said Capt . Brian Block , a spokesman for the Marines . Among other comments posted to his Facebook page , Stein called Obama a liar and suggested he would not follow some orders issued by the president . An other-than-honorable discharge is given to a Marine who commits a `` serious offense '' that significantly differs from conduct expected of a Marine , the Corps said . A statement from the Marines said it approved the findings of a military board , which in March recommended the discharge . The board found Stein violated rules limiting political conduct by service members . The Facebook page for Stein 's Armed Forces Tea Party had a post Wednesday saying the discharge will be postponed until the results of a medical condition , with which he was diagnosed Monday , are returned and treatment is discussed . `` I have spent the last 9 years honorably serving this great nation and the Corps , '' Stein wrote on his personal Facebook page . `` Even though I will be discharged no one can take the title of Marine away from me . I thank my family and friends for their support and love . Today is just the start of the rest of my life . Semper Fi . '' Stein said earlier this month that the case against him was weak , based on personal opinion and not on legal aspects . Stein , who is based at Camp Pendleton near San Diego , California , called Obama a liar in a January 26 post to the Armed Forces Tea Party Facebook page . Two days later , he said the president is `` the 'Domestic Enemy ' our oath speaks about . '' Opinion : Marine 's Facebook posts on Obama go too far . In a March 4 posting , Stein questioned Obama 's birth certificate . Another discussion on the site in March said Stein 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 previously 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 . '' While the First Amendment to the U.S. Constitution protects the free speech rights of ordinary citizens , a Defense Department rule prohibits service members from engaging in some forms of political activity . Among the prohibited activities are publishing partisan political articles or serving in an official capacity with a partisan political club . Stein has said that he carefully followed the Defense Department directive . The Facebook page notes that it does not represent and is not affiliated with the military or government . Nearly 30,000 people `` like '' Stein 's Armed Forces Tea Party page . Facebook members responding to news of Stein 's discharge Wednesday were largely supportive . `` You 've got to be kidding me . OTH 's ( other-than-honorable discharges ) are given to Marines who grossly violate the UCMJ ( Uniform Code of Military Justice ) , as in drug use , excessive DUI 's , adultery , etc . This is a joke , '' one wrote . `` So disappointed in the Corps . This is a poor decision , '' wrote another . Another Facebook member , however , said Stein 's punishment was expected . `` For any of you that thought that he was going to get anything but 'Other than honorable ' ... you really dont know jack about the military , '' he wrote . CNN 's Adam Levine contributed to this report .
