The White House is reviewing the SpaceX contract

The White House has directed the Department of Defense and NASA to gather details about SpaceX's multibillion-dollar contract after Mr. Trump and Mr. Musk publicly quarreled, according to four people familiar with the matter. The administration has initiated a review that requires agencies to scrutinize contracts awarded to Mr. Musk and his companies in preparation for possible retaliation, according to people familiar with the matter. The Pentagon is also assessing whether SpaceX's involvement in the next-generation US missile defense system should be curtailed.
