Donald Trump launches extraordinary new attack on London mayor as he accuses media of 'working hard to sell' Sadiq Khan's call for calm following terror attack

'Pathetic excuse by London Mayor Sadiq Khan who had to think fast on his "no reason to be alarmed" statement. MSM is working hard to sell it!' the president tweeted. Trump drew widespread criticism for tweeting criticism of Khan for telling Britons to keep calm and carry on after three jihadis ran over a crowd of people and stabbed several others before being shot dead. Khan was referring to an increased police presence in the British capital when he said there was 'no reason to be alarmed.'
