BOSTON - Moments after state Sen. Dianne Wilkerson's resignation letter was read in the Senate chamber Wednesday, state Senate President Therese Murray said the Senate is emerging from a trying time.

"The shadow is lifting, and in time, hopefully not too long from now, the good work of the Senate and our commitment to the people will once again be the focus of all inquiry and conversation," Murray, a Plymouth Democrat, said.

Wilkerson's resignation is the second to hit the Senate in less than a week. Jim Marzilli, an Arlington Democrat, stepped down last Friday  after details of a trip to Berlin, Germany, in October emerged. Marzilli is currently facing multiple counts of sexual harassment.

"This has been a trying time for the Senate," Murray said. "But this chamber and its members have stood too long, and served too well, to be shaken by the actions of any individual."

Murray also noted that she hopes Marzilli and Wilkerson apologize.

"I don't know if we will ever hear an apology from those who should offer one," she said. "I hope we do someday."

Ultimately, Murray reaffirmed her dedication to the Senate.

"On behalf of the Senate, I want to express my deepest belief that the moral fiber of this body is strong and unbending," she said. "And we will continue to serve our constituents and the people of the commonwealth with great pride and conviction."
