Democratic congressional candidate Lori Trahan formalized her campaign Thursday, touting a $242,000 fund-raising haul in the last two weeks of September.
Trahan, who was former congressman Marty Meehan’s chief of staff and now works as a business consultant, said the majority of her donations came from inside the district and from women.
“This is going to be a competitive race, and I plan on being competitive, so I’m optimistic about my ability to raise money and my support going forward,” she said Thursday in a phone interview.
Her announcement adds to a growing field of candidates to succeed US Representative Niki Tsongas, who has said she will not run for reelection next year.
Democratic candidates actively running or considering a bid include former lieutenant governor nominee Stephen J. Kerrigan; Boston Mayor Martin J. Walsh’s former chief of staff, Dan Koh; state Senator Barbara L’Italien; Lawrence state Representative Juana Matias; and Cambridge City Councilor Nadeem A. Mazen.
Republican businessman and political activist Rick Green has also launched a campaign.
Lowell state Senator Eileen Donoghue, a Democrat, announced this week that she would not run for the seat.
Trahan’s fund-raising news puts her far behind Koh, who last week announced more than $800,000 in donations. But her announcement appeared designed to differentiate her intake by pointing out that the majority of the cash came from inside the district.
Koh’s campaign declined to offer details about his donations, saying that it would comply with federal disclosure requirements by the Oct. 15 deadline.
