Judge's travel ban ruling 'utterly wrong'

US President Donald Trump has attacked the judge who blocked his travel ban, saying Americans should blame the courts "if something happens".

On Friday Seattle judge James Robart ruled that President Trump's ban on travellers from seven mainly Muslim nations was unconstitutional.

David Rivkin, a lawyer who served under Presidents Ronald Reagan and George H W Bush, tells the Today programme that Robart's decision is "completely indefensible".
