Trump lauds 'special' bond with Morrison

US President Donald Trump has lauded his "very special relationship" with Prime Minister Scott Morrison.

During Mr Morrison's state visit to the US, Mr Trump spoke about his relationships with the current PM and his predecessor, Malcolm Turnbull.

"I like Malcolm (Turnbull) much ... I really think they're both very good people," Mr Trump told Sky News on Sunday night.

"But I've developed a very special relationship with Scott, he's a great gentleman.

"He had the kind of election that I had, so we have something in common. It was a little bit of a surprise and it was a very big victory."

Mr Trump earlier dubbed Mr Morrison a "man of titanium" when they met at the White House.
