President Donald Trump took to Twitter to voice his concerns and frustrations about the late Senator John McCain.

"The president didn't stop tweeting all weekend on all sorts of stuff, old favorites like Robert Mueller, Joe Biden, John McCain even though John McCain passed away months ago, 'Saturday night live,' the news media, general motors, Shepherd Smith of fox and others. What impression did you get from his nonstop tweeting and retweeting over the weekend?" CNN host Wolf Blitzer asked.

"All I can say is be best, right?" CNN commentator Gloria Borger joked. "This is a presidential troll, okay? He's trolling people who are alive, people who have passed away. I think what he was doing was sitting somewhere in the White House and watching television nonstop. He is so full of grievance, he can't let anything go. And not even to someone like an American hero like John McCain. I think it's disgraceful and I think that it's immature."

Legal analyst Jeffery Toobin hinted that Trump would never learn how to "Be Best."

"How's that going?" Toobin said.

"Not too well," Borger said.

"What do you think the odds of that are?" Toobin asked.

"Zero," she said.
