- Donald J. Trump (@realDonaldTrump) September 15, 2017The travel ban into the United States should be far larger, tougher and more specific-but stupidly, that would not be politically correct!
The travel ban targeting a handful of Muslim-majority countries has been contentious since the president first proposed it in January.
In short remarks to reporters, Trump said he had been briefed on the explosion but did not elaborate on what he meant in his reference to Scotland Yard. Authorities in London are still investigating the attack, and it's not immediately clear who was responsible or what Trump was referring to in suggesting that the perpetrators were known to authorities.
The Metropolitan Police were equally quick to dismiss Trump's accusations that the force was aware of the attacker before the explosion, calling his comments "speculation". The Homeland Security report is expected to be presented to the White House in the coming weeks.
London and Washington have long boasted of their "special relationship", close ties that were strained earlier this year when the United States leaked information on an investigation into a bomber who killed 22 at a Manchester pop concert.
The Mayor of London's response comes just months after Trump called Khan "pathetic" in the wake of the London Bridge attacks, accusing him of telling Londoners there was "no reason to be alarmed".
"Another attack in London by a loser terrorist", Trump added. The internet is their main recruitment tool which we must cut off & use better!'
Trump concluded, "Must be proactive & nasty!"
He said: "The last thing I'd like to say about the investigation is that during the course of the day there has been some uninformed speculation on social media and from journalists and I would like to emphasise that is unhelpful as we try to pursue this fast-moving investigation". "We need the Travel Ban as an extra level of safety!" The Supreme Court is scheduled to hear arguments on October 10 on the legality of the bans on travelers from six mostly Muslim countries and refugees anywhere in the world.
