Key U.S. lawmaker objects to Trump 'Space Force' plan

The chairman of the U.S. House of Representatives Armed Services Committee strongly criticized President Donald Trump's plans for a new "Space Force" on Monday, setting the stage for a battle over one of Trump's favorite initiatives. Trump signed a directive in February to start the process of creating a new branch of the military dedicated to handling threats in space, which has become an applause line at the Republican president's campaign rallies. Legislation to create the branch requires congressional approval.
