"We've got to take a hard look at the role that the Russians played in this election process. We'll see where the investigation goes. But for Donald Trump to summarily dismiss all of this makes no sense to me at all."
The Washington Post reported on Friday that a secret CIA assessment concluded Russia intervened in the presidential election to help Trump win the White House.
Trump in an interview that aired Sunday blasted the recent report, saying he thinks it's "ridiculous" and "just another excuse."
"I don't believe it," the president-elect said in an interview that aired Sunday on "Fox News Sunday."
"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."
Sanders said on Sunday he is focused on making sure the president-elect fulfills the promises he made during the campaign.
