Biden, 75, has not yet decided if he's going to run for president. The New York Times reported that he has met with Los Angeles Mayor Eric Garcetti (D) and Montana Gov. Steve Bullock (D), and urged both to decide on a 2020 campaign without considering the former vice president's plans.

Biden's appearances on the campaign trail are expected to coincide with those of former President Obama.

Biden has made periodic appearances in the year and a half since leaving office, largely to promote his book. He has often spoken out against Trump, and condemned the president's rhetoric toward women and minorities.

While Biden ultimately opted not to run in 2016, he is widely considered a potential 2020 candidate for president. He has thus far been noncommittal, saying he may decide by the end of the year.

A poll released in late June found almost one-third of registered Democratic voters back Biden for the party’s 2020 presidential nomination.
