David Grosso, a top aide to Del. Eleanor Holmes Norton, has taken a job with CareFirst BlueCross BlueShield.

Grosso will be vice president for public policy for the region’s largest health insurer. He has been Norton’s legislative director since early 2007, when he left the employ of former Ward 6 Councilmember Sharon Ambrose after she stepped down. He had worked for Ambrose for six years, including a stint as clerk of the economic development committee.

LL has heard some grumbling about the move, given that in recent weeks Grosso, representing Norton, had sat in on strategy sessions with Wilson Building staffers and other stakeholders regarding a council bill intended to squeeze community benefits out of CareFirst—-legislation the insurer has vigorously opposed. The meetings, LL is told, concerned strategies to avoid congressional meddling with the bill.

Ward 3 Councilmember Mary M. Cheh, who introduced the bill and is pushing it through the council, declined to comment directly on the personnel shuffle, but she did say that she plans to make several amendments to her CareFirst bill that she hopes to pass at the next legislative meeting, on Dec. 2. Those amendments, she says, are intended to allay concerns from suburban jurisdictions—-and, in the unspoken subtext, to head off any possible congressional intervention.

Grosso had no comment, but CareFirst spokesperson Michael Sullivan says that his new gig isn’t a lobbying job, but “primarily a policy analysis, review, [and] development post.”

Grosso is leaving Norton’s office Friday and will start his new job on Dec. 1.
