Executive orders; loves the pen doesn’t matter what the consequences are.
Check it out:

President Barack Obama on Thursday authorized the Pentagon to call up reserve and National Guard troops if they are needed to assist in the U.S. response to the Ebola outbreak in West Africa.

Obama signed an executive order that allows the government to call up more forces and for longer periods of time than currently authorized. There is no actual call-up at this point.

The U.S. has committed to send up to 4,000 military personnel to West Africa to provide logistics and humanitarian assistance and help build treatment units to confront the rapidly spreading and deadly virus.
