Joe Biden in The Mueller Report

On Principles & Values: We had to wait until after election to tell about it

BIDEN: In retrospect, there is something. We were informed by the director of central intelligence, that there was evidence that they were interfering in electoral process, trying to break in everything from machines, to changing voter registration. That was in August; Barack Obama was worried, if we spoke out against it, without having more proof and support, then what would have happened is they'd say we're trying to interfere in the election. And so it wasn't until after [the election]--before we left the White House--that we knew the detail of how deep they were. But we went to the Republican leadership in the House, they said, "no, we don't want any part of pointing this out." We had clear, overwhelming circumstantial evidence that it was being done. And Obama did confront Putin, saying that stop it. Putin denied he was doing it. We believed he was doing it.
