US President Donald Trump announced on Monday he is sending a top official to Minnesota as outrage grew over his administration’s militarised immigration raids and the shooting dead of a second protester in Minneapolis.

Trump said that Tom Homan, his point man for border security, would arrive in the state later and “will report directly to me”.

The high-profile assignment suggested that the 79-year-old Republican president is seeking to regain control over a rapidly deteriorating political and security situation.

Minneapolis has become ground zero in the clash between Trump and growing numbers of Americans over his nationwide immigration crackdown.

A federal judge in Minneapolis was to consider on Monday whether the deployment of federal officers – many of them masked, heavily armed and unidentified – violates the state of Minnesota’s sovereignty.
