After more than two years of consistent trips to presidential battleground states, daily television and radio appearance, and growing whispers over the past six months, East Bay Rep. Eric Swalwell will finally announce Monday night that he is running for the Democratic nomination for President of the United States.

Swalwell teased the announcement in a Twitter post Monday afternoon showing him running through a park in New York City.

Although Swalwell is viewed as an extreme long-shot for winning the nomination, among the roughly 17 candidates already in the run, his appearance is one of the more high-profile. The CBS late-night talk show is the highest-rated in its time slot.

By contrast, Ohio Rep. Tim Ryan announced his own campaign for president last week with little fanfare. Candidates like Sens. Kamala Harris, Amy Klobuchar, Bernie Sanders, and Elizabeth Warren, meanwhile, have made their announcements at large public events.

Swalwell is expected to bask in the glow of his nascent presidential campaign this weekend with a rally in Dublin, his hometown. The event is scheduled for April 14, 2 p.m. at Dublin High School, Swalwell’s alma mater.

Swalwell’s congressional campaign website, however, has not fully changed over. His well-used red, white, and blue campaign logo remains, but the list of events already notes his early campaign schedule featuring town halls in Iowa, South Carolina, and Nevada–three early primary and caucus states.
