Why has Trump sent in National Guard?published at 16:03 British Summer Time 8 June
US President Donald Trump has said earlier that protests that stop immigration laws being enforced "constitute a form of rebellion" against the US government.
Under Title 10 of the US Code - the collection of the general and permanent federal laws - presidents can federalise the National Guard - meaning to order the state-based troops to active duty - when there is "a rebellion or danger of a rebellion" against government authority. Trump has used this power to send 2,000 National Guard members to Los Angeles.
In a statement from the White House, Trump said National Guard members would "temporarily protect ICE and other United States Government personnel who are performing Federal actions".
The statement also says they will be deployed for 60 days, with the final decision resting with the US secretary of defence.
