Trump has got Defiance Disorder* say his aides

*That means he can’t help doing whatever they most strongly urge him NOT to do – according to yet another tell-all book

DOnAlD Trump’s aides have diagnosed him with ‘Defiance Disorder’ to explain his impulsive behaviour, a new book claims.

The US President’s advisers are said to believe their boss often does the opposite of what they tell him to do.

The claims are made in a new book, by US journalist Howard Kurtz, that paints a portrait of a leader driven by impulse.

It comes weeks after the release of Michael Wolff’s Fire And Fury, which Mr Trump tried to ban, and is expected to make a series of claims that are just as damaging.

Fire And Fury questioned Mr Trump’s mental state and described chaos in the White House, prompting the President to brand Wolff ‘mentally deranged’.

In a passage from the latest book, Media Madness, Kurtz writes that when the White House finished a review on transgender individuals serving in the military last July, they agreed with the President to wait before deciding how to proceed. Instead, and behind his aides’ backs, Mr Trump, 71, tweeted his own decision that his government would not allow them to serve.

Then- chief of staff Reince Priebus was reported to have said: ‘Oh my God, he just tweeted this,’ as colleagues scrambled to respond. In another episode, Mr Trump is said to have ‘blindsided’ staff by tweeting – without any evidence – that his predecessor Barack Obama had wiretapped him during the election campaign.

Kurtz, a host on Trump’s favourite TV channel Fox news, says that after dozens of such incidents, aides came up with the term ‘Defiance Disorder’. Some have speculated this could be a reference to Oppositional Defiant Disorder (ODD), a recognised psychiatric condition in children. Those with the condition are ‘ very quick to lose their tempers, apt to ignore or rebel against rules, quick to blame others for mistakes or misbehaviour’, according to the US Child Mind Institute.

The nHS says 5 per cent of children are diagnosed with the problem, which can be treated with therapy and medication.

According to details of the book released to the Washington Post yesterday, Mr Trump’s daughter Ivanka, who is also an adviser, had a fraught relationship with her father’s former chief strategist Steve Bannon.

It says that, during one fight, Mr Bannon – a key source for Wolff’s book – told Miss Trump: ‘You love your dad. I get that. But you’re just another staffer who doesn’t know what you’re doing.’ During one Oval Office meeting, Mr Bannon reportedly blamed Miss Trump for a leak. Her father supported him over her, saying: ‘Baby, I think Steve’s right here.’

Media Madness, which is released next week, also claims Mr Trump conceded he was wrong to make former Press secretary Sean Spicer defend the size of his inauguration crowd to the media.

His aide Kellyanne Conway is said to have advised against it. Kurtz writes: ‘She invoked a line that she often employed when Trump was exercised over some slight: “You’re really big,” she said. “That’s really small.”’

He ignored her, however, and Mr Spicer’s attacks on the Press for accurately reporting the crowd size became a subject of ridicule. Afterwards Mr Trump is said to have told Mrs Conway: ‘You were right. I shouldn’t have done that’.

A White House official denied the book’s claims, saying: ‘The past three weeks have made very clear who the leakers are.’
