ABOARD A U.S. MILITARY AIRCRAFT (Reuters) - Acting U.S. Defence Secretary Patrick Shanahan said on Saturday he had not yet determined whether a border wall with Mexico was a military necessity or how much Pentagon money would be used.

President Donald Trump on Friday declared a national emergency in a bid to fund his promised wall at the U.S.-Mexico border without congressional approval.
