Former Vice President Joe Biden will address House Democrats at their three-day retreat next week, according to a report.

Sources told Politico that Biden will headline the event in Cambridge, Md. The retreat is scheduled to start next Wednesday, and the former vice president will speak to the caucus on the first day of the gathering.

Though it’s currently unknown what the former vice president will discuss before the Democrats, Biden could speak about how the party works to win the support of middle-class voters in the midterm elections, according to the report.

Biden is considered a potential contender for the 2020 presidential race, and he hasn’t explicitly ruled out a run.
