Former Vice President Joe Biden teased a presidential run on multiple morning shows Monday while promoting his new book, “Promise Me, Dad.”

When asked on the Today show about a presidential run, Biden said, “I honest to God haven’t made up my mind about that. I’m not closing the door. I’ve been around too long.”

Rumors of him continuing a political career resurfaced last week when former head of the DNC Donna Brazile suggested she wanted to replace failed presidential candidate Hillary Clinton with Biden after concerns about her health arose.

But Biden says he wouldn’t have agreed to replace Hillary Clinton as the Democratic presidential nominee under any circumstances.

Biden tells NBC’s “Today” show he had decided not to run last year, and says, “I would have never done that.”

He was asked about Brazile’s book, to which Biden says, “I wouldn’t have taken” Clinton’s place as the party’s standard-bearer.

Biden says he was for Clinton, but that he worried about her prospects. He says not long before the election, “It hit me like a ton of bricks, there was no discussion of Issues” in her campaign.

Only time will tell if Biden will attempt to defeat President Trump in 2020.

He said, “I’m a great respecter of fate, but who knows what the situation is going to be in a year and a half? I don’t have any idea. I’m in good shape now, I’m in good shape… but I just don’t know. Honest to God that’s the truth.”
