President Donald Trump is exploring whether he can legally deport U.S. citizens to foreign prisons, according to CNBC. That includes El Salvador’s mega-prison, where hundreds of alleged gang members have already been sent. White House press secretary Karoline Leavitt said Tuesday the proposal is under legal review and would apply only to the most violent, egregious, repeat offenders.” The Trump administration has deported over 200 alleged foreign gang members from the U.S. to prisons in El Salvador.
