Obama immigration: Republicans condemn president's plan

US President Barack Obama has laid out some of the most sweeping changes to the US immigration system for decades in a televised address.

Republican Speaker of the House John Boehner condemned the use of executive powers, accusing the president of acting "like a king or emperor".
