ESPN “First Take” co-host Stephen A. Smith reacted Monday to San Antonio Spurs coach Gregg Popovich bashing President Donald Trump this weekend.

Smith said Trump has “attributed” to the country becoming a divided nation with his behavior.

“[Trump] is tweeting attacks on Stephen Colbert and Lord knows who else,” Smith said while chuckling. “As petty as it gets.”

Smith went on to say Trump has not been acting like a grown-up, which he believes is a “problem.”

He continued, “As a result, if you are Popovich, if you know nothing else about Popovich, the one thing that he is intolerant about is pettiness. And so, a lot of times when people are watching us talk about this right now, understand we are not talking about a party. We’re not talking about elected officials. We’re talking about the behavior of an individual who is 70 years of age that some people look at and say he is engaging in stuff reserved for 15 and 16-year-olds. That is a problem.”

“When you are the leader of the free world, who representing all of us, the one requirement that I think is universally understood is that people expect you to be a grown-up. And if you are not conducting yourself like a grown-up, it’s going to have a profound effect on the people you supposedly represent because they don’t like the fact that your behavior is emblematic, supposedly, of what we are when we are not that way.”
