Washington (CNN) Congressional investigators asked then-Secretary of State Hillary Clinton, along with 17 other Cabinet secretaries, whether she used a personal email in 2012, a question she ignored. 
  
 Clinton's email practices have come under sharp scrutiny in the wake of the revelation that she exclusively used a private domain name and server to conduct public business while at State. 
  
 The question came in a Dec. 13, 2012, letter, obtained by CNN and first reported by the New York Times , from Rep. Darrell Issa, then-chairman of the House Committee on Oversight and Government Reform, to an array of Cabinet secretaries. It was part of an investigation into the email policies and procedures imposed by the Obama administration on its officials.

 "Have you or any senior agency official ever used a personal email account to conduct official business?" Issa wrote in the form letter. "If so, please identify the account used."

 But Mrs. Clinton did not reply to the letter. And when the State Department answered in March 2013, nearly two months after she left office, it ignored the question and provided no response. 
  
 The query was posed to Mrs. Clinton in a Dec. 13, 2012, letter from Representative Darrell Issa, the Republican chairman of the House Committee on Oversight and Government Reform. Mr. Issa was leading an investigation into how the Obama administration handled its officials’ use of personal email. |||||
A:
Just when you thought Hillary Clinton's email brouhaha had moved on to other things, the New York Times uncovers an old letter congressional investigators sent Clinton asking about her email use. In the letter dated Dec. 13, 2012, House Oversight Committee chair Darrell Issa explicitly asks whether the then-secretary of state "or any senior agency official ever used a personal email account to conduct official business" and requests that the accounts be identified. He also asks about "alias" accounts and text messages, CNN reports. Clinton never replied and left the State Department weeks later on Feb. 1, 2013. On March 27 of that year, the department described its policies for personal email use for Issa, as he had also requested. "Employees may use personal email on personal time for matters not directly related to official business, and any employee using personal email 'should make it clear that his or her personal email is not being used for official business,'" the State Department's assistant secretary for legislative affairs wrote. A rep refused to answer questions yesterday about why it avoided mentioning Clinton's email use. However, a Clinton aide says "her usage was widely known to the over 100 department and US government colleagues she emailed, as her address was visible on every email she sent." Issa's initial letter was part of an investigation spawned when administration and EPA officials were found to be using private accounts for government business.
