Mark Townsend and Julian Borger report:

Aides to Donald Trump, the US president, hired an Israeli private intelligence agency to orchestrate a “dirty ops” campaign against key individuals from the Obama administration who helped negotiate the Iran nuclear deal, the Observer can reveal.

People in the Trump camp contacted private investigators in May last year to “get dirt” on Ben Rhodes, who had been one of Barack Obama’s top national security advisers, and Colin Kahl, deputy assistant to Obama, as part of an elaborate attempt to discredit the deal.

Watergate much?

Although sources have confirmed that contact and an initial plan of attack was provided to private investigators by representatives of Trump, it is not clear how much work was actually undertaken, for how long or what became of any material unearthed.

Neither is it known if the black ops constituted only a strand of a wider Trump-Netanyahu collaboration to undermine the deal or if investigators targeted other individuals such as John Kerry, the lead American signatory to the deal. Both Rhodes and Kahl said they had no idea of the campaign against them. Rhodes said: “I was not aware, though sadly am not surprised. I would say that digging up dirt on someone for carrying out their professional responsibilities in their positions as White House officials is a chillingly authoritarian thing to do.”

Trump is every inch an authoritarian.
