A top US immigration official is expected to leave the US city of Minneapolis in what may mark a shift in the White House's tone after the fatal shooting of a second US citizen by federal officers over the weekend, BBC reported.

As Border Patrol Commander Gregory Bovino and some immigration agents depart, "border tsar" Tom Homan will begin leading on-the-ground efforts in the Minnesota city after the shooting of Alex Pretti on Saturday escalated tensions. 

The decision by President Donald Trump may indicate the administration's interest in walking back more aggressive federal action in his nationwide immigration crackdown, according to BBC.
