Patrick defends Mass. Lt. Gov. Murray

BOSTON (AP) - Lt. Gov. Timothy Murray says he is cooperating with an investigation into possible campaign finance violations and is prepared to return any improper donations.
  
On Thursday, the state Office of Campaign and Political Finance made public a letter it sent in September to Attorney General Martha Coakley, saying there was evidence Murray and his political committee broke the law by accepting donations raised by former Chelsea Housing Authority Director Michael McLaughlin.
  
Murray told reporters in Worcester on Friday that he is ready to take responsibilities for any mistakes that were made.
  
The lieutenant governor also said that it was family considerations, and not the fundraising controversy, that prompted his recent decision not to seek the Democratic nomination for governor in 2014.
  
Gov. Deval Patrick said Friday he has full trust in Murray.
