House Select Committee on Benghazi Chairman Trey Gowdy said Tuesday it may still be “technically possible” to retrieve thousands of emails to and from former Secretary of State Hillary Clinton on the private server her lawyer said was “wiped clean.”

Clinton used a private email account and server located in her New York residence to conduct official government business throughout her tenure as the nation’s chief diplomat. David Kendall, her lawyer, told Gowdy Friday that the emails are no longer accessible by the server’s cleaning.
