While most world leaders sent their condolences after men armed with knives killed 7 people and injured 50 others, Trump was busy picking a Twitter fight with London Mayor Sadiq Khan.
"He's really, really something else. I mean, just after an attack on London, he shit on the mayor of London," Noah said on "The Daily Show Monday night." "You're suffering, and Donald Trump is shitting on you. Like, 'Donald, the accident left me totally blind.' 'At least you won't see your wife ever again! She's a two at best!' 'Donald, I start chemotherapy tomorrow.' 'Thank God! You always had the worst hair.'"
The post prompted a swift response from one of Khan's spokespeople: "He has more important things to do than respond to Donald Trump's ill-informed tweet that deliberately takes out of context his remarks urging Londoners not to be alarmed when they saw more police - including armed officers - on the streets."
