Hillary Clinton still struggling to shake off controversy over deleted emails
Controversy may distract from bid for Democratic presidential nod
Hillary Rodham Clinton wiped her email server "clean", permanently deleting all emails from it, the Republican chairman of a House of Representatives committee investigating the deadly 2012 attacks in Benghazi said.
Congressman Trey Gowdy said the former secretary of state had failed to produce a single new document in recent weeks and had refused to relinquish her server to a third party for an independent review, as Gowdy had requested.
Clinton, the presumptive frontrunner for the Democratic presidential nomination, faced a Friday deadline to respond to a subpoena for emails and documents related to the 2012 attacks in a US diplomatic compound in Benghazi that killed four Americans, including the US ambassador to Libya.
The attention to Clinton's use of a private email account and server has threatened to become a distraction as she prepares to launch her campaign.
Clinton's attorney, David Kendall, said Gowdy was looking in the wrong place.
In a six-page letter released late on Friday, Kendall said Clinton had turned over to the State Department all work-related emails sent or received during her tenure as secretary of state from 2009 to 2013.
