US border patrol chief 'forced out'

The US Border Patrol chief has been forced out a day after President Donald Trump announced an ambitious plan to build a wall at the Mexican border and hire 5,000 Border Patrol agents, according to a US official.

Mark Morgan told senior Border Patrol agents about his removal during a brief video conference on Thursday morning, saying he was asked to leave and that he decided to resign rather than fight the request, according to the official.
