WHAT THEY'RE SAYING
"I am very saddened to hear about the indictments that have just come down against Mayor Sheila Dixon. My prayers go out to her and her family. I am confident that she will be found not guilty of all the charges that have been brought against her. During her tenure as Mayor, she has done a remarkable job in continuing the renaissance of the City of Baltimore."
State Sen. Nathaniel J. McFadden, chairman, Baltimore Senate delegation
"Mayor Dixon is an effective public servant who has worked tirelessly for the citizens of Baltimore. I wish Mayor Dixon the best as this difficult case continues and allegations are answered as part of the legal process. My prayers are with the Mayor and her family during this challenging time."
Stephanie C. Rawlings-Blake, City Council president
"The City of Baltimore has made solid progress under Mayor Dixon. This is a tough day for all of us who care about Baltimore's progress, and for Mayor Dixon and her family. It is my sincere hope that all of these long drawn out matters will soon be resolved in a court of law once all the facts are known."
Gov. Martin O'Malley
"This is a sad day for Baltimore City Mayor Sheila Dixon and a sad day for Baltimore. We must allow the legal process to run its course and remember that Mayor Dixon is innocent until proven otherwise. Sheila Dixon has been an excellent Mayor. She's been a good steward for Baltimore with a reputation for a can-do attitude and follow-through."
Sen. Barbara A. Mikulski
"Mayor Dixon and her family are in my thoughts and prayers."
Rep. Elijah E. Cummings
"Once again the culture of corruption is rearing its head amongst Maryland Democrat politicians. Of course these two are innocent until proven guilty, but the loose ethics of that we have seen exposed this past year. Maryland needs leaders that will hold themselves to a higher standard and not abuse the public trust. Change is definitely in order for Baltimore, Annapolis and Maryland as a whole.
James Pelura, chairman, Maryland Republican Party
"Everybody needs to remember that this is an indictment, not a conviction. Sheila has done a commendable job as mayor and the city and the region are better for it. Special prosecutors have a mixed record getting convictions and it is not easy."
George from Bel Air, commenter on baltimoresun.com
"Ms. Dixon was ethically challenged long before she became mayor. It appears that she's been cleaning up her act recently, now that the spotlight is on her and she has more to lose. Although she has turned out to be a pretty good mayor, no one is above the law and she should pay the price for the tricks she pulled when she thought no one was watching."
Debbie from Baltimore, commenter on baltimoresun.com
"I think the Prosecutor should be run out of town if this is all he has come up with after 2003. ... Pathetic."
Buz, commenter on baltimoresun.com
"[Dixon was never] a favorite of mine, and never cast a vote for her. But I give the lady credit: she's made some good choices for city government priorities, and hired some very skilled people to implement solutions. I'm sorely disappointed by the behavior the indictment describes, but as a city taxpayer, I'm also sorry to see her leadership crippled."
