Former Vice President Joe Biden stopped in Vermont Sunday as part of a tour to promote his new book.

His book, "Promise Me, Dad: A Year of Hope, Hardship, and Purpose," chronicles the year after his son, Beau, died of brain cancer.

Biden is considered to be a front-runner for the Democratic nomination for president in 2020, but he has yet to formally announce any decision to run.

During an appearance at the Flynn Center in Burlington, Biden spoke about the struggle after his son's death in 2015 and the process of moving forward with his family.

Members of the media were not allowed to record audio or ask Biden questions. Instead, Biden took questions from author Jodi Piccoult.

Biden said he wrote the book to tell the world about his son, Beau, and show people that it is possible to go on after the loss of a loved one.

Biden said he was prepared to run for president in 2016, but backed away after his son's illness and death.

Supporters in Burlington were excited to hear from the former vice president.

"I think he's an honest person in an environment today where honesty, I feel like, we are lacking. He is somebody I believe is honest and has the best interests of the country at heart," Jeff Smith said.

"He his charisma. He's awesome and I think what he's doing is great, " Rebecca Chamberlain said.

Biden says that he believes he is the most qualified person to be president.
