George Conway, an attorney and husband of White House counselor Kellyanne Conway, unveiled a new nickname for President Trump early Thursday, going after "Deranged Donald" on Twitter.

"Deranged Donald is at back at it again. 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," Conway wrote on Twitter, including the hashtag #DerangedDonald.

Conway was responding to a Wednesday report from The Washington Post about Trump's suggestion that the United Kingdom had helped the Obama administration spy on his 2016 presidential campaign.

Conway also wrote that "Deranged Donald" does not read books composed of the "accurate, highly valuable, top secret information" compiled for him because they don't "have lots of pictures and tell him how great he is."

"Plus Deranged Donald doesn't really need all those books because Fox News," the frequent Trump critic added.

Trump on Wednesday tweeted about a former CIA analyst's comment suggesting the U.K. spied on his campaign.

One America News Network political correspondent Neil McCabe had said on air that ex-CIA analyst Larry Johnson told him "it is time for the American people to learn the truth about how the British government helped the Obama administration dodge the Fourth Amendment by spying on the 2016 Trump campaign for them."

Johnson said that the U.S. and British governments communicated about Trump campaign adviser George Papadopoulos, who pleaded guilty in 2017 to lying to the FBI.

Attorney General William Barr said earlier this month that he believed "spying" took place on the Trump campaign. He later clarified that he was concerned about possible improper surveillance and vowed to look into the matter.

Trump's tweet came one day after The White House announced that Trump would embark on his first official state visit to the U.K. in June, a visit that will coincide with D-Day ceremonies commemorating the 75th anniversary of the Allied invasion of Europe during World War II.
