Former Vice President Joe Biden is floating the idea of a potential run for the presidency in 2020, bringing up the subject in a meeting with longtime aides.

The Associated Press reported that Biden told a few foreign policy aides during a planning meeting for the Penn Biden Center for Diplomacy and Global Engagement that a 2020 run was a “real possibility,” but insisted that he had not made a decision yet to run.

The former vice president also reportedly expressed interest in recruiting those in the room to work on his 2020 campaign if he decided to run, but would not be too upset if any staffers decided they did not want to leave their positions outside the government.

The meeting was intended to set the 2018 agenda for the diplomacy center.

Biden recently told NBC News in an interview that he would decide on the 2020 bid if it was “the right thing to do.”

“I’m focused on one thing: electing a Democratic Congress to stop this erosion of the core of who we are,” Biden said. “I’ll look at that a year from now. I have plenty of time to consider whether or not to run.”

The former vice president has made other moves that have stoked rumors that he is preparing for a 2020 presidential run.

In July 2017, Biden launched the “American Possibilities” PAC with the goal of helping congressional and gubernatorial candidates nationwide. The move, however, also fueled speculation that he is trying to gain the support of many donors and candidates should he run for president in the future.
