Callers clash over @POTUS travel ban #TrumpBan #BBCNolan

Donald Trump has sacked his top lawyer - after she said her department wouldn't defend his controversial temporary travel bans. Sally Yates, who was acting attorney general, had told her staff she didn't think the 90 day ban on visitors from seven mainly-Muslim countries was lawful. Here, more than one-and-a-half million people have signed a petition calling for Donald Trump's state visit to the UK to be cancelled - though Downing Street say the visit will go ahead. Last night thousands of people held demonstrations in British cities in protest over his immigration policies. Stephen talks to commentators Charlie Wolff and Lata Sharma.
