Gee...I believe Britain is still a sovereign nation, and Cameron owes no apology to anyone in or out of American government. Indeed, we owe him many apologies for the disgusting behavior of our current putz in chief.
I don’t think threatening allies is a good way to start a run for the highest office of the land. Once a bully........?
Trump didn’t say Cameron owed him an apology. One of his foreign policy advisors did.
