“The only person who is been on a steady incline and continuing to gain momentum and gain support seems to be Elizabeth Warren. There couldn’t be better news for President Trump," Sanders said.

"The far-left radical ideas that she’s bringing to the table are just not going to sell in most of America. And I think that is a great thing … for the country — because it helps make sure that we get four more years under this president," she added.

Sanders went on to predict that Warren would not make a pivot towards more centrist policies after winning the contentious Democratic primary, which has seen battles over progressive ideas such as Medicare-for-all.

"Elizabeth Warren, I don’t think she wants to come back to the middle," Sanders said. "I think she believes that the far left side is right. I think it’s a scary thing for America if she became president.”
