The Trump administration has brought a Qaeda suspect to the United States to face trial in federal court, backing off its hard-line position that terrorist suspects should be sent to the naval prison in Guantánamo Bay, Cuba, rather than to civilian courtrooms.

The suspect, Ali Charaf Damache, was transferred from Spain and was scheduled to appear Friday in federal court in Philadelphia, making him the first foreigner brought to the United States to face terrorism charges under President Trump. A court clerk confirmed that Mr. Damache was due to appear Friday afternoon.
