Border Patrol agents and Immigration and Customs Enforcement officers who have worked together side by side for two decades are increasingly at odds in a battle to see who can better carry out President Donald Trump’s deportation operation.

In addition, Border Patrol Chief Mike Banks disclosed to the Washington Examiner in an exclusive interview this month that his agents are now deployed across at least 27 cities carrying out immigration enforcement.
