Spurs coach Gregg Popovich has offered his opinion many times about the direction of this country and the actions of President Donald Trump.

Popovich may have taken his frustrations to another level Monday, calling the sitting president a "soulless coward." 

After hearing the President's remarks as to why he did not mention the four U.S. soldiers killed in ambush in Niger, Popovich called The Nation and went on a rant expressing his frustration with Trump. The reporter, Dave Zirin, wrote he has "never heard this man so frustrated, so fed up, and so tense with anger than today."

The comments that sparked the conversation came when Trump said, "President Obama and other presidents, most of them didn’t make calls, a lot of them didn’t make calls. I like to call when it’s appropriate, when I think I’m able to do it."

Popovich, who served in the Air Force and is the head coach for the U.S. national team, started the phone conversation by saying, "I want to say something and please just let me talk and please make sure this is on the record.

"I’ve been amazed and disappointed by so much of what this President had said, and his approach to running this country, which seems to be one of just a never ending divisiveness," Popovich continued. "But his comments today about those who have lost loved ones in times of war and his lies that previous presidents Obama and Bush never contacted their families, is so beyond the pale, I almost don’t have the words.

"This man in the Oval Office is a soulless coward who thinks that he can only become large by belittling others. This has of course been a common practice of his, but to do it in this manner–and to lie about how previous Presidents responded to the deaths of soldiers — is as low as it gets. We have a pathological liar in the White House: unfit intellectually, emotionally, and psychologically to hold this office and the whole world knows it, especially those around him every day.

"The people who work with this President should be ashamed because they know it better than anyone just how unfit he is, and yet they choose to do nothing about it. This is their shame most of all."
