Ever since he kicked off his campaign for president, Donald Trump has made a habit out of creating new, or extending old, rivals with politicians, the media, and even celebrities. After Trump unloaded on mark cuban on Sunday morning, the owner of the Dallas Mavericks answered back.

Cuban on Trump

During the course of the 2016 presidential election, Mark Cuban was outspoken in his opposition to Donald Trump. After originally giving the former host of "The Apprentice" a chance, Cuban quickly reversed course, and eventually endorsed Hillary Clinton in the general election.

With Cuban being a billionaire himself, the rivalry between the two money men came naturally. Earlier this week, Cuban spoke out against Trump and his recent "Muslim ban," which didn't sit well with the new commander in chief. "I know Mark Cuban well. He backed me big-time but I wasn't interested in taking all of his calls," Trump tweeted, before saying Cuban was "not smart enough" to even run for the presidency. As seen on his offical Twitter account on February 12, the co-host of the reality show "Shark Tank" is now giving his response.

Initially replying with a simple "LOL," Mark Cuban was then asked by a follower what the back story was to his actual feud with Donald Trump.

"I don't know," Cuban answered on Twitter, before rhetorically asking and throwing shade at Trump by noting, "But isn't it better for all of us that he is tweeting rather than trying to govern?"

Trump's Twitter

Days after he pulled off the upset and defeated Hillary Clinton on Election Day, Donald Trump addressed his social media use during an interview with CBS' "60 Minutes." In response, Trump vowed to become "very restrained" once he entered the White House, but that doesn't appear to be the case.

In the three weeks that he's been the leader of the free world, Trump has only increased his presence on Twitter, often starting his day by airing his grievances on his social media feed. Backlash often results, but Trump has been adamant about using Twitter as his number one form of communication, which has become even more vital as his war of words with the mainstream media heat ups.
