Britain and the United States have become embroiled in a diplomatic row over the British Ambassador Sir Kim Darroch, who has been critical of Donald Trump.

Darroch branded the Trump administration "inept" and "dysfunctional" in memos which were leaked by a Sunday newspaper, leading to a hostile response from Trump on Twitter.

As well as labelling Darroch a "wacky ambassador" and "a very stupid guy", he also hit out at Theresa May's "foolish" way of dealing with Brexit.

Cal Thomas and Marion McKeone discussed this and more from the United States, including billionaire Jeffrey Epstein being charged with federal sex trafficking crimes, and whether the World Cup-winning US women's soccer team will be invited to the White House.
