While Congressman Stephen Lynch (D-South Boston) isn’t expected to make a formal announcement until later this afternoon, a new Stephen Lynch for Senate Facebook page showed up this morning with a link to a “Stephen Lynch for US Senate Announcement” YouTube video that announces Lynch’s Senate candidacy. Earlier in the morning, the Stephen Lynch for Congress Facebook page had posted a message directing people to the newly created Senate page for news “on today’s plans and schedule.”

Lynch is expected to make an announcement at 4 p.m. this afternoon at the Ironworkers Local 7 Hall in South Boston.

Lynch would be the second Democrat running for the unexpired term left vacant by John Kerry’s confirmation to Secretary of State earlier this week. Congressman Edward Markey (D-Malden) announced his intentions to run back in late December.

While there is still speculation that former Senator Scott Brown (R-Wrentham) is showing interest in the seat, there is still no official word if he will jump into the race.
