The Trump administration has transferred hundreds of immigrants to El Salvador even as a federal judge issued an order temporarily barring the deportations under an 18th century wartime declaration targeting Venezuelan gang members, officials said Sunday. Flights were in the air at the time of the ruling.

U.S. District Judge James E. Boasberg issued an order Saturday temporarily blocking the deportations, but lawyers told him there were already two planes with immigrants in the air — one headed for El Salvador, the other for Honduras.
