Jake Tapper led an interview with Romney on Sunday by asking the senator to respond to these events.

“What will Senate Republicans do to make sure none of this madness happens?”

“It’s not going to happen. It’s going nowhere,” Romney answered. “It’s really sad in a lot of respects and embarrassing because the president could, right now, be writing the last chapter of this administration with a victory lap with regards to the vaccine.”

Romney went on to say Trump “could be going out championing this story. But instead, he’s leaving Washington with conspiracy theories and things that are so nutty and loopy that people are shaking their head wondering in the world has gotten into this man? I think that is unfortunate because he has more accomplishments than this last chapter suggests he’s going to be known for.”
