That comes as Donald Trump has plans to transfer foreign citizens who had been convicted in the states there. Built to house up to 40,000, the mega-prison is described as a ‘concrete and steel pit’ where ‘no inmates ever leave’ and there is an explanation why.

The Trump administration and the president of El Salvador said they struck a deal allowing the U.S. to ship detained migrants and imprisoned criminals to a mega-prison there.

The beds themselves have no mattresses, meaning the CECOT prisoners have to sleep on hard metal, and besides 30 minutes of exercise, there is essentially nothing for the inmates to do besides read one of the two bibles in each of the crowded cells.

Salvadorean President Nayib Bukele said his administration is willing to take in "only convicted criminals" in exchange for a fee

After meeting Secretary of State Marco Rubio, El Salvador's president has offered to house U.S. deportees and even American inmates in his country's "mega-prison."

Migrants deported from the US, and even “dangerous” American citizens convicted of heinous crimes could be headed to a notorious hellhole prison in El Salvador, where inmates live in over-crowded cells and rival gang members fight to the death over food and water.
