WASHINGTON—The Trump administration is planning to invoke a sweeping wartime authority known as the Alien Enemies Act in an effort to speed up deportations, according to an official familiar with the discussions.

Donald Trump is preparing to invoke the Alien Enemies Act of 1798 in order to speed up the process of mass deportations, four familiar sources have told CNN. The law gives the president enhanced authority to remove undocumented immigrants.
