President Trump and Senator John McCain continue to ramp up their media war, after Senator McCain called the US President's raid in Yemen a failure.

The Yemen raid left one Navy SEAL and a number of civilians dead.

White House spokesman Sean Spicer said the raid was a success, and anyone critical of it was doing a disservice to the fallen SEAL.

Hours later, John McCain went on NBC News to say it's fair to criticize a mission for failing and still hold respect for those who serve, referencing his own life experience about a failed mission to save him from a prisoner camp in Vietnam.
