​P​resident Trump doubled down on his criticism of the London mayor’s ​”no reason to be alarmed” remark by saying Sadiq Khan had to “think fast” to cover up his comments.

“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!​,” Trump tweeted on Monday, referring to the mainstream media.

The president initially blasted Khan in a Sunday tweet after the mayor while addressing Saturday’s terror attack that killed seven tried to reassure citizens not to panic when they noticed heightened police activity on the city’s streets.

​”Londoners will see an increased police presence today and over the course of the next few days. There’s no reason to be alarmed,” Khan said.

But Trump, misinterpreting what Khan said, shot off a tweet.

“At least 7 dead and 48 wounded in terror attack and Mayor of London says there is “no reason to be alarmed!”​,” Trump wrote Sunday. ​

Asked to respond, a spokesman for Khan called ​the president’s ​tweet “ill-iniformed.”

“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,” the spokesman said.

White House spokeswoman Sarah Huckabee Sanders said Trump was “not trying to pick a fight” with Khan even if the “media wants to spin it that way.”
