How does that happen, asks Trump after Christa Pike's failed execution

Reacting to the failed execution of Tennessee woman Christa Pike, US President Donald Trump asked, “How does that happen?” "Should be easy to do. It shouldn't be very difficult," he added. Pike remained alive after two doses of pentobarbital and has now been taken to a medical facility. She was executed for the murder of a 19-year-old in 1995.
