U.S. President Donald Trump on Thursday named Joseph Maguire as acting national intelligence director, part of a leadership shake-up at the agency that oversees 17 U.S. spy agencies.

Trump said he would soon announce another nominee to oversee America's 17 civilian and military intelligence agencies.

The U.S. Department of Defense says the development of anti-satellite laser weapons by China and Russia is among the key concerns necessitating the need for a U.S. Space Force.
