President Donald Trump has suggested sending people who are attacking Tesla to prisons in El Salvador if they are convicted of crimes, as a number of the automaker’s vehicles and showrooms have been targeted by reported arson and other violence.

Trump’s comments appear to be referencing a deal his administration made with El Salvador to deport alleged Venezuelan gang members from the U.S. to serve out their jail time. Rights groups have criticized the deal, citing harsh conditions in Salvadoran prisons.
