George Conway, husband to White House adviser Kellyanne Conway, went off on a Twitter rant Thursday morning attacking President Donald Trump, bestowing him with a new nickname: "Deranged Donald".

The conservative lawyer — and high-profile Trump critic — was set off by a report that the president promoted a baseless accusation that the United Kingdom helped the Obama administration spy on his campaign — just one day after accepting an invitation for a state visit to Britain from Queen Elizabeth II.

"Deranged Donald is at back at it again," Conway wrote. "Deranged Donald can do things like this and it's not even the top of the news, because it gets lost beneath all of the other deranged things Deranged Donald does."
