WASHINGTON (AP) — Edward Markey of Massachusetts has become the Senate's newest member after serving 37 years on the other side of the Capitol in the House.
The 67-year-old Democrat was sworn in to replace John Kerry, who resigned from the Senate earlier this year to become secretary of State.
Last month Markey defeated Gabriel Gomez, a 47-year-old businessman and former Navy SEAL, in a special election. He will fill out the rest of Kerry's term, which expires in January 2015, meaning he would have to run again in November of 2014 for a full six-year term.
A leading House legislator in the fields of energy and communications, Markey was eighth in seniority in the House. He now becomes the junior senator from Massachusetts, behind fellow Democrat Elizabeth Warren.
