Trump has accused the New York Times of committing "treason" after the paper published the article on Wednesday, which claimed that a coalition was at work within the administration to thwart Trump's "worst inclinations". "[Donald Trump] has a clear governing vision for the country and his record of results is remarkable".

The president dismissed the article as "gutless" and potentially treasonous, and said his administration was a "well-oiled machine".
The Justice Department declined to confirm or deny an investigation.
Mr Trump has reportedly demanded that aides find out who wrote the piece.
He said it was a "disgrace" for the newspaper to have published the op-ed from a purported senior administration official. "We'd like to think that the Senate wouldn't allow it, but we can't be sure".
