Well, it seems Australia has also been subjected to Trump pressure for personal political gain. According to the New York Times:
President Trump pushed the Australian prime minister during a recent telephone call to help Attorney General William P. Barr gather information for a Justice Department inquiry that Mr. Trump hopes will discredit the Mueller investigation, according to two American officials with knowledge of the call.
And like the call to Zelensky, this one also went into the super secret server.
And Barr is in it up to his (not pencil-thin) neck:
President Trump initiated the discussion in recent weeks with Mr. Morrison explicitly for the purpose of requesting Australia’s help in the Justice Department review of the Russia investigation, according to the two people with knowledge of the discussion. Mr. Barr requested that Mr. Trump speak to Mr. Morrison, one of the people said. [emphasis added]
The cracks are widening, folks!
