IRS denies searching emails without warrant

The head of the Internal Revenue Service denied that his agency searches people's e-mails without a warrant.

"The short answer is we are not taking that position," Steven Miller, the IRS acting commissioner, said in response to questioning from Sen. Chuck Grassley (R-Iowa) during a hearing. Miller said that for criminal investigations, his agency obtains a search warrant before requesting the contents of emails from an Internet service provider. He said investigators do not request email content information from service providers for civil investigations.
