That message was echoed by David Lammy, a lawmaker for the opposition Labour Party, who believed Trump was shaken by the prospect of being "met by millions of us out on the streets protesting".
"Beyond the disagreements between leaders and the optics of this cancellation, U.S. -UK relations continue to remain strong - largely because there are a wide range of institutional ties between the nations in military cooperation, intelligence, economics, and commerce that operate as normal despite the political storms that may arise", Mahaffee said.
