Trump calls for deporting some citizens to El Salvador, testing US law

US President Donald Trump said on Monday he wants to deport some violent criminals who are US citizens to Salvadoran prisons, a move that experts said would violate US law.

Trump’s comments marked the clearest signal yet that the US president is serious about deporting naturalised and US-born citizens, a proposal that has alarmed civil rights advocates and is viewed by many legal scholars as unconstitutional.

Trump said he would only go through with the idea if his administration determined it was legal.
