Enter Mayor Marty

Martin J. Walsh was sworn in today as Boston's 48th mayor — the city's first new chief executive in 20 years. Walsh promised to listen, and to be a mayor to every neighborhood, race and religion in Boston.

Walsh took the oath of office at Boston College, his alma mater, in front of his mother, his girlfriend, city councilors, Governor Deval Patrick, senators, members of Congress, and thousands of other onlookers. He pledged to strengthen the city's economy, improve its public schools, and increase government trust and transparency.

WBUR's Anthony Brooks and Sacha Pfeiffer review the day's inaugural events and discuss the changes Walsh may usher in.

WBUR, "Walsh stressed inclusiveness in moving the city forward. 'We are in this together,' he said. The former state representative and labor leader also promised to continue to listen to constituents. 'I will listen. I will learn. I will lead,' he said."

WBUR, "Walsh announced the appointment of Daniel Arrigg Koh, general manager of online video channel HuffPost Live, as his chief of staff Saturday. And on Sunday, he said departing City Councilor At-Large Felix Arroyo will serve as his chief of health and human services."
