Trumpies latest tweet-storm is about him not going to London because he doesn't want to cut the ribbon at Obama's crappy new embassy. Bad location, bad architecture, etc.
Of course all the decisions about the new embassy were made by the Bush administration, but let's not let a little thing like the facts get in the way of a good tweet!
I heard the real reason he won't go is that he wanted to ride in a horse-drawn carriage like the Queen, and they said no.
