(CNSNews.com) - President-elect Donald Trump is dismissing press reports that Russia helped him win the presidency by hacking and releasing Democrat National Committee emails but withholding hacked RNC emails.
"I think it's ridiculous," Trump told "Fox News Sunday. "I think it's just another excuse. I don't believe it. I don't know why, and I think it's just -- you know, they talked about all sorts of things. Every week, it's another excuse. We had a massive landslide victory, as you know, in the Electoral College. I guess the final numbers are now at 306."
"Do you think the CIA is trying to overturn the results of the election somehow to weaken you in office?" host Chris Wallace asked Trump.
"Well, if you look at the story and you take a look at what they said, there's great confusion. Nobody really knows.
"And hacking is very interesting. Once they hack, if you don't catch them in the act, you're not going to catch them. They have no idea if it's Russia or China or somebody. It could be somebody sitting in a bed some place. I mean, they have no idea."
Wallace asked Trump why the CIA would put out information that the Russians wanted him to win.
"I'm not sure they put it out," Trump responded. "I think the Democrats are putting it out because they suffered one of the greatest defeats in the history of politics in this country. And, frankly, I think they're putting it out. It's ridiculous.
"We ought to get back to making America great again, which is what we're going to do. And we've already started the process."
Trump said the U.S. intelligence agencies are "fighting among themselves" because even they are not sure that the Russians were involved in the DNC hacking.
"But if you read the stories, the various stories, they're disputing. And certain groups don't necessarily agree. Personally, it could be Russia. It -- I don't really think it is. But who knows? I don't know either. They don't know and I don't know."
Senate Armed Services Committee Chairman John McCain (R-Ariz.) said on Sunday he plans to investigate the claim that Russia interfered on behalf of Trump.
Sen. Ben Cardin (D-Md.), the ranking member of the Foreign Relations Committee, told CNN's "State of the Union" he's "glad there's bipartisan interest to make sure that we do an investigation. We need to find out exactly what has happened," Cardin said.
"What we do know is that Russia hacked us. That, we do know. What we do know, that they made information available during the election in order to have an impact on our election.
"What we need to do now is have that type of investigation to find out what we should do about Russia. Russia is not our friend. They have interfered in Europe. They have compromised the boundaries of European countries. They have attacked Europe institutions. And now they have attacked America. We have got to take action."
