In the excitement of the news conference, you may have forgotten the rally that's happening nearby on Whitehall.
But Green Party MP Caroline Lucas would not let the Foreign Office gathering rain on her parade.
Addressing the crowd at the protest, Ms Lucas said of Mr Trump: "This is a man who is not worthy of our respect, he is not worthy of the office of president and we say go home."
"We stand in solidarity with all of those that recognise that our future is green or it is not at all," she added.
She said Mr Trump was "best friends with Nigel Farage and Boris Johnson", prompting boos from the crowd.
Ms Lucas also said the president was "no friend of Britain", adding: "We know that Britain is better than the Britain that has been pimping out the royal family for photo opportunities for Trump."
