Hillary Clinton this afternoon defended her use of a personal email account during her time at the State Department.

At the time, she said she opted “for convenience” in using one email account, which was allowed by the State Department. Looking back, she said it probably would have been better to use a second email account, “but at the time, this didn’t seem like an issue.”

Rep. Trey Gowdy (R-S.C.), chairman of the House Select Committee on Benghazi, responded with a written statement, saying "serious questions" remain about this issue. 

Read his response below and tune in tonight at 7p ET as Gowdy goes "On the Record" with Greta Van Susteren. 

“Having finally heard from Secretary Clinton about her exclusive use of personal email with which to conduct official business while serving as Secretary of State, regrettably we are left with more questions than answers. For instance, there remain serious questions about the security of the system she employed from a national security standpoint, who authorized this exclusive use of personal email despite guidance to the contrary from both her State Department and the White House, who had access to the server from the time Secretary Clinton left office until the time—almost two years later—the State Department asked for these public records back, and who culled through the records to determine which were personal and which were public.

“Without access to Secretary Clinton’s personal server, there is no way for the State Department to know it has acquired all documents that should be made public, and given State’s delay in disclosing the fact Secretary Clinton exclusively used personal email to conduct State business, there is no way to accept State’s or Secretary Clinton’s certification she has turned over all documents that rightfully belong to the American people. That is why I see no choice but for Secretary Clinton to turn her server over to a neutral, detached third-party arbiter who can determine which documents should be public and which should remain private. Secretary Clinton alone created this predicament, but she alone does not get to determine its outcome. These public records at issue are broader than Libya and broader than Benghazi. The Secretary of State has enormous responsibility and jurisdiction and the public, the media and Congress have a legal right to access these public records without impediment.

“Because Secretary Clinton has created more questions than answers, the Select Committee is left with no choice but to call her to appear at least twice. The first appearance will be to clear up her role and resolve issues surrounding her exclusive use of personal email to conduct official business. This is necessary to establish our Committee has a complete record with respect to Secretary Clinton’s time in office. Our committee will then call her to appear before the Committee in a public hearing to answer questions specifically regarding Libya and the Benghazi terrorist attacks that took the lives of our four brave fellow citizens.”
