(CNN) — President Donald Trump pressed Australia’s Prime Minister during a recent phone call to help Attorney General William Barr with his review of the origins of the Russia probe, according to an official familiar with the call. The call happened with Barr’s knowledge and at his suggestion, says the official. The New York Times first reported this call. The official notes this is seeking assistance with the review, which is being conducted by US Attorney John Durham, and so is seen as appropriate and completely different from the Ukraine matter. Justice Department officials say that it is appropriate for the attorney general and the President to seek help from foreign countries with an investigation of 2016 election interference. Durham is examining what intelligence came from other countries that propelled the investigation that eventually became the Trump-Russia probe. An official briefed on the matter said the attorney general has asked the President to request the help of several countries, including Australia, with the Durham review. Officials believe that requesting foreign help with a retrospective look at 2016 election interference differs vastly from Trump’s request made in the Ukraine call transcript released last week.
