LAWRENCE, Mass. (AP) - U.S. Sen. Elizabeth Warren has sworn-in Lawrence Mayor Daniel Rivera at a public inaugural ceremony attended by about 600 people.
The Saturday morning ceremony marked the public transfer of power from William Lantigua, who did not attend the event after conceding the mayor's race to the former city councilor.
U.S. Rep. Niki Tsongas, state Treasurer Steve Grossman and State Auditor Suzanne Bump joined mayors from around Massachusetts as well as supporters and well-wishers who gathered at a public auditorium for the inauguration.
Tsongas told the crowd that she has long believed that Rivera has the right mix of leadership, ideas and experience to lead Lawrence. She said the new mayor demonstrated the courage necessary to stand up and be a forceful and effective voice for change.
Rivera has pledged to work for all residents of Lawrence.
