Sunday, Rep Senator Bob Corker tweeted it was "a shame the White House has become an adult day care". Wednesday morning, after NBC News reported that Trump had alarmed members of his administration by requesting a tenfold increase in the USA nuclear arsenal - which he categorically denied as "pure fiction" and "fake news" - he had tweeted that it may be "appropriate" to challenge network news licenses.
Mr Tillerson last week refused to confirm that he had called the President that, and Mr Trump has said that those reports are fake news.
Donald Trump decides to go into full dictator mode and say, "We're going to possibly consider revoking your license to broadcast here in the United States". The federal government is not allowed to interfere with what the media reports.
The National Association of Broadcasters said Trump taking retaliatory regulatory action against NBC and other networks violates the Constitution's protection of freedom of the press, established in the First Amendment.
But Trump wouldn't be able to revoke any licenses from news networks. NBC essentially creates the content and then local stations air it, no matter what it is.
In his earlier tweet, the President had asked, albeit rhetorically, when it was appropriate to start challenging news outlets' licenses. During its coverage of the Watergate scandal, President Richard Nixon tried to do the same with the Washington Post Co. A State Department spokesperson later denied Tillerson used that word to insult Trump.
