McCain works to undermine Trump 8 years after destroying GOP, 8 years after getting crushed by Obama in 2008.

Sen. John McCain (R-Ariz.) said Thursday that he spoke to the Australian ambassador to express support for the nations' relationship after a heated call from President Trump.

"I called Australia’s Ambassador to the United States this morning to express my unwavering support for the U.S.-Australia alliance," McCain, who's frequently criticized Trump, said in a statement.
