From the Daily News:
PHONES BELONGING to City Controller John Liu were among those secretly wiretapped during a probe into his campaign fund-raising operation that dated to 2009, new court papers revealed Monday.
The feds had 10 wiretaps on six different phones belonging to Liu and several others connected to his campaign for more than 18 months in 2010 and 2011, according to the documents filed in Manhattan Federal Court.
The wiretaps intercepted thousands of calls from March 2010 to September 2011, the filing by lawyers for former Liu campaign Treasurer Jia (Jenny) Hou notes.
Her attorney, Gerald Lefcourt, said the investigation of Liu began in 2009 when a confidential source approached the FBI with information about a campaign donor. Liu began serving as controller in January 2010.
