Prosecutors say John Kerry's eldest daughter won't be charged with drunken driving in Los Angeles.
Police arrested Alexandra Kerry in Hollywood last week on suspicion that she was driving under the influence.
Los Angeles city attorney spokesman Frank Mateljan says prosecutors declined to pursue a case due to insufficient evidence. He says they didn't offer further details.
A spokeswoman for John Kerry said last week that the Massachusetts senator's daughter was pulled over for an expired registration and released after a breathalyzer test showed her blood-alcohol level was under the legal limit.
Mateljan says Alexandra Kerry isn't facing any other charges. The 36-year-old has produced documentaries and has had several small acting roles.
