The White House has barred several major broadcasters and newspapers from attending an informal press briefing.
The BBC, CNN, the New York Times and others were excluded from an audience with Press Secretary Sean Spicer, with no reason given.
It came hours after President Donald Trump delivered another attack on the media in a speech, saying that "fake news" was the "enemy of the people".
He has previously singled out CNN and the New York Times for criticism.
I don't blame Trump for excluding the members of the press who won't report what is said accurately and publish unfounded drivel. If our politicians showed the same the same courage, the Daily Mail, which Trump also excluded, would go out of business as a newspaper within a month and become even more of a gossip magazine than it is now.
I've always had the impression that the BBC is biased on certain issues, anti Israel, anti Farage and UKIP, pro the EU, and I would certainly add anti Trump to that list.
