Trump has done what journalists should have done: boycotted the White House Correspondents’ dinner

The most dangerous place in Washington DC, the old joke goes, is between a politician and a television camera. It’s a wonder there are any such places left, so intimate have the third and fourth estates become. Periodically, American journalism gets itself into a funk over its proximity to power and the consequences for integrity and neutrality.

Iraq was supposed to be The Line. The press corps concluded in retrospect that it had been too credulous about the Bush administration’s claims. It failed to scrutinise the case for war, the intelligence on weapons of mass destruction, and the preparations for post-war reconstruction. This would never be allowed to happen again, we were assured; but self-reproof without reparation is mushy self-help, the ego is massaged but the soul unsaved.
