Why would the Trump administration leak information about the unfriendly call he had with the Australian Prime Minister on Saturday?

My speculation is here:

Nick Nicholas’ answer to Do Americans agree that the Prime Minister of Australia should have been treated the way he was by President Trump during their first phone call?

TL;DR: domestic consumption, as being America First and Tough On Muslim Refugees. Especially if he ends up honouring the deal Obama made after all.
