Billionaire businessman Mark Cuban has no reason to believe President Trump’s campaign colluded with the Russians in last year’s election.

“The Russians had no effect on the election. Look, if you spotted Donald Trump two pieces of bread and behind him was a refrigerator full of ham, he couldn’t collude with the Russians to make a ham sandwich. Right?” Cuban told columnist Maureen Down in a report published Friday.

The 59-year-old tech mogul and Dallas Mavericks owner has fought Trump in a war of words since the campaign and explained Trump as three personalities in one.

“There are three Donald Trumps,” Cuban said. “Donald Trump, the president. Donald Trump, the salesperson. Donald Trump, the troll. Trolls are going to troll.”
