I find it hard to believe. More likely Obastard is looking for an excuse to replace them with his loyal cronies.
The first rule of tyrants is to make sure the military is loyal to you in any showdown. Many have speculated about where the US military would stand in any serious attempt to remove Obama by force. You can bet that he has had his functionaries doing all they can to make sure the DOD will support him in any actions he may take.
