AUGUSTA, Maine — Former Vice President Joe Biden, a potential Democratic presidential candidate in 2020, will visit Portland in late January as part of a national tour.

The Jan. 31 event at Portland’s Merrill Auditorium was posted on Biden’s official Facebook page Monday. The 75-year-old’s last public appearance in Maine was as Colby College’s commencement speaker in May.

Biden, who was a Delaware senator for 36 years before becoming vice president under former President Barack Obama in 2009, is promoting his new memoir, “Promise Me, Dad: A Year of Hope, Hardship, and Purpose,” which details the 2015 death of his son, Beau, from cancer.

His “American Promise Tour” is being billed as “a series of conversations that will go beyond the 24-hour news cycle and 280-character arguments to connect friends and neighbors around the topics that matter most.”

More than two years ago, Biden flirted with the idea of a 2016 presidential run before ruling it out. Republican Donald Trump went on to beat Democratic candidate Hillary Clinton.

Biden said in November that he may run in 2020, if “no one steps up,” according to the Associated Press.
