Marcia Murphy, a spokeswoman for the U.S. attorney's office in Maryland, said under federal law, the government must notify anyone whose communications were intercepted — including those who were not targets of an investigation but who spoke with a target whose phone was wiretapped. She declined to comment on the letters.
FBI Baltimore spokesman Dave Fitz said the wiretaps were part of an ongoing investigation. He said he could not comment on the scope of the investigation or how many people received the notices.
A copy of the March 8 notice obtained by The Baltimore Sun states that the wiretaps took place from Oct. 16, 2013, to March 8, 2014, and again between March 11, 2014, and March 25, 2014.
The "target telephone" number in the notice is redacted.
The notice was sent from the office of U.S. Attorney Rod J. Rosenstein and signed by Assistant U.S. Attorney Kathleen O. Gavin, who oversees the office's fraud and public corruption section. It tells those notified to direct any inquiries to FBI Special Agent Steven Quisenberry.
Mohler said thosewho received the letter include County Administrative Officer Fred Homan, Deputy Administrative Officer Donna Morrison and Arnold Jablon, who heads the Department of Permits, Approvals and Inspections.
He said Kamenetz did not receive one.
"Members of the county executive's staff have been assured that they are not in any way subject to an investigation," Mohler said.
County officials don't know what or whowas being investigated as part of the wiretap, he said.
County Council Chairman Tom Quirk, a Catonsville Democrat, Councilwoman Vicki Almond, a Reisterstown Democrat, and Councilman David Marks, a Perry Hall Republican, all said they received the letter and called the FBI.
They all said they were told that they were not part of the investigation.
