John McCain: an unlikely ally.

On Monday, Donald Trump held a ceremony at the White House to honor the bravery of the Navajo code talkers, who served alongside U.S. Marines during World War II.

But even as he praised their service, Trump couldn't help injecting politics into the mix, using the event to slam Democratic U.S. Senator Elizabeth Warren, whom he regularly refers to derogatorily as 'Pocahontas':

"I just want to thank you because you are very, very special people. You were here long before any of us were here. Although, we have a representative in Congress they say was here a long time ago -- they call her Pocahontas! But you know what, I like you. You are special people."

The backlash to Trump's comment was fierce, but perhaps no one captured the outrage we felt at that moment better than Senator John McCain, whose tweet both honored the code talkers and slammed Trump for politicizing the moment:

And Twitter was clearly standing with McCain...

Some couldn't help but recall that Trump himself has never served:

And Don felt Trump's choice of backdrop for the ceremony was another intentional slight:
