Glenn Beck is not with those whom have sworn some version of the following oath of enlistment. Citing the oath for an officer in the U.S. Army, for example:
"I, _____ (SSAN), having been appointed an officer in the Army of the United States, as indicated above in the grade of _____ do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign or domestic, that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservations or purpose of evasion; and that I will well and faithfully discharge the duties of the office upon which I am about to enter; So help me God." (DA Form 71, 1 August 1959, for officers.)
He will not support and defend the Constitution against a domestic enemy, who owes allegiance to foreign sovereigns.
At 3:40, Glenn Beck states:
"But if you want to go down that road, go down that road, I am not with you." -- Glenn Beck
