Story highlights Trump spent Thursday on the defensive over some of his laudatory comments about Vladimir Putin

Trump also said Libertarian Gary Johnson should not be in the debates

Washington (CNN) Donald Trump gave an interview Thursday that aired on a television station funded by the Kremlin, arguing that the Russian government was "probably" not meddling in the American presidential race.

Speaking to Larry King on RT America, which is an arm of government-funded news outlet Russia Today , Trump said it would "not be appropriate" if Russian forces were looking to influence the race, which is suspected by some investigators and has been fanned by Hillary Clinton's campaign as recently as Thursday morning.

He also suggested that the allegation was politically motivated.

"I think it's probably unlikely. Maybe the Democrats are putting that out -- who knows," Trump told King. "If they are doing something, I hope that somebody's going to be able to find out so they can end it. Because that would not be appropriate at all."

Jason Miller, a Trump spokesman, told CNN the interview was recorded as a podcast and was a favor to King, adding, "Mr. Trump was never told it would be shared anywhere else." Miller later said Trump wouldn't have agreed to do the interview had he known it would be aired on RT.
