"I'm not going to tell you that he and I are best friends, but we are friends. I have talked to him on and off for the last many years, was sitting down alone with him in the Oval Office on more than one occasion. I have talked to him on the telephone every now and then," Sanders said.
"He is an icon, clearly, in the Democratic Party and I have absolute confidence that he will play a vigorous, vigorous role -- I think he had said this in the campaign. And, we need him. No question about it. We need him," he noted.
"And, if I win, I'm sure he will be there at my side. If somebody else wins, he will be there at their side," Sanders stated.
"People shouldn't underestimate Bernie Sanders," Lisa Boothe urged on "Fox & Friends" Friday. "He's probably going to win Nevada. He heads into South Carolina with some serious momentum at his back."
"If he is the nominee for the Democrats, what would Barack Obama do?" asked Steve Doocy.

Recent headlines in the media don't exactly inspire confidence in the relationship between the two politicians.
That said, Sanders could also be counted on as a reliable vote to continue the Obama administration's most important initiatives, including the Affordable Care Act (ACA). Sanders has campaigned on implementing a Medicare-for-all system, which has led to criticism from a powerful labor union in Nevada, site of Saturday's Democratic caucuses.
Additionally, the former president has refused to publicly support or criticize Sanders or any other candidates -- notably his own vice president, Joe Biden -- in the 2020 race.
