President Obama on Thursday accused Donald Trump of spinning conspiracy theories about America's election system with his claims that the election is "rigged" against him.

Obama at first said he was at a loss for words in trying to figure out what Trump was trying to say.

"If Mr. Trump is promoting a conspiracy theory that is being propagated across the country, including in places like Texas where typically it's not Democrats that are in charge of voting booths, that's ridiculous, that doesn't make any sense, and I don't think anybody would take that seriously," he said during a press conference at the Pentagon.

He also poked fun at Trump for acting like a sore loser months before the election is over.

"I've never heard of somebody complaining that they got cheated before the game was over or before the score was even tallied," he said. "My suggestion would be go out there and try to win the election."

"If Mr. Trump is up 15 points before Election Day, and he ends up losing … then he can raise some questions … but that doesn't seem to be the case right now," he added.
