The Trump administration is reshuffling the leadership of its immigration enforcement operation and scaling back the federal presence after a second fatal shooting by Immigration and Customs Enforcement (Ice) officers. President Donald Trump said he was placing his border tsar, Tom Homan, in charge of the mission, with Mr Homan reporting directly to the White House, after Mr Bovino drew condemnation for claiming the man who was killed, Alex Pretti, had been planning to "massacre" law enforcement officers, a characterisation that authorities had not substantiated.
