President Donald Trump waves as he arrives at the White House, Thursday, Sept. 14, 2017, in Washington.
In short: Trump is more than willing to jump to conclusions when he can comfortably fit an incident like what happened in London this morning into his existing world view. Passenger Luke Walmsley said it was "like every man for himself to get down the stairs."PHOTOS: Explosion on London train " People were just pushing", he added. Britain has seen four other terrorist attacks this year, which killed a total of 36 people.
"I'm going to call the prime minister right now", Trump said. "It keeps going and going, and we have to be very smart and we have to be very, very tough perhaps we're not almost tough enough", Trump told reporters in the Rose Garden of the White House.
The brief statement did not say if the two discussed Trump's tweet. He adds: "Must be proactive & nasty!"
A manhunt is under way after the improvised explosive device (IED) sent a fireball through a packed London Underground train carriage in south west London during the Friday morning rush-hour. The incident left 18 people injured but no one seriously hurt.
Trump also took the opportunity to push his proposed travel ban against several Muslim-majority nations, which has been tied up in court.
Trump's travel ban has been ensnared in the courts since the president's first attempt to enact the policy in January.
President Donald Trump has made it a habit of taking to Twitter to air his thoughts before he has all the facts. He says it should be "tougher and more specific".
Trump's comment was described as "unhelpful speculation" by London's Metropolitan Police.
Under the order, foreign nationals are banned for 90 days from six countries - Iran, Syria, Sudan, Somalia, Libya, and Yemen - and refugees lacking a link to the USA are barred for 120 days.
President Trump was quick on the draw following Friday's terrorist attack on a London train, calling for what appears to be below-the-belt responsive action.
On Twitter, Trump promoted his handling of extremist militants and said the government should cut off the internet to such groups.
On that occasion, May was forced to upbraid the U.S. leader, saying "I think Donald Trump is wrong in what he said about Sadiq Khan" after the London Bridge attack.
Trump referred to the potential attacker as "another loser terrorist".
In his next post, Trump seemingly called for the internet - "their main recruitment tool" - to be "cut off".
