4. Biden's team was warned about announcing 2020 bid on same day as forum focused on women of color

(CNN)Former Vice President Joe Biden's team was warned this week that it would be a bad idea to announce his presidential campaign on the same day as a forum focused on women of color.

Biden's team had considered releasing a video announcing his 2020 campaign on Wednesday, the same day as the She the People Presidential candidate forum, according to two sources who had conversations with aides to the former vice president. The She the People event is focused on issues affecting women of color, a core constituency of the Democratic Party.

The sources, both critically involved with the forum, tell CNN they advised members of Biden's team on the mission of the She the People event and the poor optics of overshadowing the forum with his video release.

"Wednesday is an important day to Democratic women of color," one of the sources relayed to CNN about the conversation. "It would be a bad idea to stand in the way."
