Republican senator says ‘credibility’ of ICE and DHS are ‘at stake’ as calls come from both sides of political divide

Pressure mounted on Donald Trump’s administration on Sunday to fully investigate the previous day’s killing by federal immigration officers of 37-year-old nurse Alex Pretti in Minneapolis.

Calls for an investigation have come from all sides of the political divide after video analysis showed officers had removed from Pretti a handgun he was reportedly permitted to carry – and which he was not handling – before fatally shooting him.

Republican US senator Bill Cassidy said the “credibility” of Immigration and Customs Enforcement (ICE) and the US Department of Homeland Security (DHS) were “at stake”.
