President Trump said Wednesday that former national security adviser Susan Rice may have committed a crime by asking for the names of who were mentioned on intercepted communications and that other Obama officials may also have been involved, The New York Times reported.

“I think it’s going to be the biggest story,” Trump told the paper in an interview in the Oval Office.

He declined requests for evidence for his allegations or the names of other Obama administration officials.

“It’s such an important story for our country and the world. It is one of the big stories of our time,” he said.

He also refused to say whether he had reviewed new intelligence to supports his claim but pledged to explain himself “at the right time.”

When asked if Rice, who has flatly denied leaking the names of Trump associates under surveillance by US intelligence agencies, had committed a crime, the president said, “Do I think? Yes, I think.”
