White House: Trump has been ‘briefed on the situation in the UK’

“The president has been briefed on the situation in London,” Spicer said. “He just spoke to Prime Minister May.”

The White House released a readout of the call, saying Trump spoke with May “to offer his condolences on today’s terror attack in London and his praise for the effective response of security forces and first responders. He pledged the full cooperation and support of the United States government in responding to the attack and bringing those responsible to justice.”

“We obviously condemn today’s attack in Westminster, which the United Kingdom is treating as an act of terrorism,” Spicer said during the briefing. “And we applaud the quick response that the British police and their first responders made to the situation. And the victims in this are in our thoughts and prayers. The city of London and her majesty’s government have the full support of the U.S. government responding to the attack and bringing those to justice who are responsible. We will provide you with further updates as warranted.”

In a statement, the Department of Homeland Security also said it “stands in solidarity alongside our friends in the United Kingdom in condemning the terrible attack at Parliament today.”

“With our partners in federal law enforcement, we are in close contact with our British counterparts to monitor the tragic events and to support the ongoing investigation,” the statement read. “At this time our domestic security posture remains unchanged. However, our frontline officers and agents continue to stay vigilant in safeguarding the American people and our homeland.”

Earlier Wednesday, during a meeting at the White House in the Roosevelt Room, Trump said: “Hearing some big news having to do with London, it just happened.”
