President Donald Trump attacked Mavericks owner Mark Cuban in a tweet on Sunday morning, saying Cuban isn't "smart enough to run for president."
In his tweet on Sunday, Trump falsely claimed Cuban had supported him "big–time" during the campaign but that Trump "wasn't interested in taking all of his calls." (Cuban openly supported Hillary Clinton.)
It's hardly the first time Trump has tweeted about Cuban, though it's his first tweet about the Mavs owner since he became President.
Cuban responded with a couple tweets of his own.
Trump has tweeted about Cuban nearly 50 times.
