Markey to run for MA Senate seat

NBC News confirms the news that Massachusetts Congressman Ed Markey (D) will seek the U.S. Senate seat being vacated by John Kerry, who's been nominated to be President Obama's next secretary of state.

Markey was first elected to Congress in 1976 at the age of 30, and he represents a district in the Boston suburbs. He's the third-ranking Democratic member of the House Energy and Commerce Committee.

On the Republican side, all eyes are fixed on whether outgoing Sen. Scott Brown (R) -- who was defeated in November -- will also seek Kerry's Senate seat in a special election.
