President Donald Trump accused Sen. Chris Van Hollen of political grandstanding after the Maryland Democrat managed to meet this week with an immigrant who had made a life in his state before being wrongfully deported to El Salvador last month.

President Donald Trump has been testing the boundaries of his authority over US immigration policy since he began his second term of office, but he hinted at taking things to a new level when he said he’d support deporting US citizens to a prison in El Salvador.

The President escalated a fight with the Supreme Court over a wrongfully deported man, proposing to send U.S. citizens to El Salvador next.
