Washington: The Wall Street Journal, accused by some journalists of going soft on US President Donald Trump, printed a stinging editorial on Wednesday that likened the falsehood-addicted commander-in-chief to an alcoholic.

Trump doesn't even drink.

The Journal editorial board ripped into the President for what it described as his "seemingly endless stream of exaggerations, evidence-free accusations, implausible denials and other falsehoods", and reserved special criticism for his unsubstantiated charge that former president Barack Obama wiretapped Trump Tower during the campaign.

Even after FBI director James Comey testified before Congress this week that his agency does not have "any information that supports" the claim, Trump has not relented.
