US immigration agents may have breached "protocol" in Minneapolis before shooting dead a nurse during protests, President Donald Trump's senior aide Stephen Miller said Tuesday, days after branding the victim an "assassin."
Deputy Chief of Staff Miller said in a statement to AFP that the White House had provided "clear guidance" that extra personnel were sent to Minnesota to "create a physical barrier between the arrest teams and the disruptors."
"We are evaluating why the CBP (Customs and Border Protection) team may not have been following that protocol," Miller said.
