Mark Cuban to Trump: 'Just Read a Book' Instead of Tweeting

President Donald Trump should take more relaxing actions than sending tweets about National Football League players over their kneeling during the national anthem, according to Mark Cuban, the billionaire investor.

"Instead of getting on his phone and tweeting, just read a book," Cuban said Monday on CNBC's "Squawk on the Street."

"You know, just chill," Cuban, the owner of the National Basketball Association's Dallas Mavericks, said in the CNBC interview.

"I know that's crazy to say about our president," he added.

The investor added that he believed Trump would not take back his words. "The president is not going to apologize. Are you kidding me?"

Cuban also commented on the issue on Sunday, tweeting that if they want to keep politics and sports separate, politicians should not accept donations from athletes.
