Senator Lindsey Graham (R-S.C.) said that it will not be difficult to find out whether Susan Rice committed a crime when she reportedly requested the unmasking of Trump associates caught in surveillance activity.

Graham said on "The O'Reilly Factor" that his Senate committee requested testimony from several Obama-era figures, including former CIA Director John Brennan and ex-Director of National Intelligence James Clapper.

He said they agreed to testify just once, and in that time, he said he will ask them flatly whether Rice made a request of them to unmask the names.

With that question, he said it will be "easy to figure out" if Rice committed a crime or was simply acting properly in her role as national security adviser.

He remarked that Rice would be unlikely to plead the Fifth because in her statements to the press, she has maintained she didn't do anything wrong.

Bill O'Reilly said such investigations will be strictly partisan, as Democrats do not want to impugn the Obama administration in any way.

Graham said that Sen. Sheldon Whitehouse (D-R.I.) and a few others will likely hear Rice's case in a nonpartisan way.
