Unrest is spreading in the US over immigrant deportations. 

Donald Trump is sending hundreds of US Marines and has ordered 2000 more National Guard troops to go to LA's immigration protests. 

California Governor Gavin Newsom's called the US President's orders deranged and has filed a lawsuit. 

US Correspondent Richard Arnold told Mike Hosking of the 2000 National Guard troops deployed, only 315 were mission assigned, the other 1700 having no particular responsibility. 

He says that 100 arrests have been made, but no charges have been laid.
