This BBC (Lefty biased) News article fails to mention if these Venezuelans were in the USA illegally or not. Most likely criminal illegals since they did get deported. Then, it goes on to say these Venezuelans were falsely accused of being gang members simply because of their gang tattoos. Really? I can only imagine what these guys tried to tell ICE in regard to their tattoos. "Honest Officer, we only got these tattoos because we thought they (tattoos) were a really cool fashion statement, we're not gangbangers". If anybody believes that bs story, I have some prime property I'll sell you in the Florida Everglades.
This article doesn't mention the time period that this all happened but may have been during the period when Venezuela refused to take deportees from USA. If that's the case, then they wound up in El Salvadore because their home country abandoned them.
This article has way too many holes in it which I suspect was done on purpose to throw shade on Trump which shouldn't surprise anyone since BBC is just the British version of CNN or NBC.
