WASHINGTON - US President Donald Trump on Friday said the United States was not going to take Turkey's detention of US Christian pastor Andrew Brunson "sitting down," a day after his Treasury chief said Washington could hit Ankara with further sanctions."They should have given him back a long time ago, and Turkey has in my opinion acted very, very badly," Trump told reporters at the White House. "So, we haven't seen the last of that. We are not going to take it sitting down. They can't take our people."
