In mid-January, House Science, Space and Technology Committee Chairman Lamar Smith (R-Texas) sent letters to four companies that played roles in maintaining and protecting Clinton’s personal server.

The letters have caught McCarthy’s attention, who told reporters he believed those inquiries should have been purview of the House Select Committee on Benghazi, chaired by Rep.

“I have the same impression as you, that it would be Gowdy's jurisdiction,” McCarthy said Monday afternoon, when asked whether Gowdy’s panel should be overseeing the investigation.

McCarthy then repeated his answer verbatim when pressed on whether Smith had given the Republican leader a heads up before sending the letters.

Monday night, Mike Long, a spokesman for McCarthy, clarified.

"The Select Committee's focus is on emails pertaining to the attack in Benghazi," he said. "The FBI is investigating all other issues related to her private server and email account."

Clinton, the front-runner for the Democratic presidential nomination, has been knocked for her use of a private email server during her time as head of the State Department.

She used a private email address hosted on a server registered to her Chappaqua, N.Y., home instead of an official government account. The arrangement alarmed security experts and raised questions about whether sensitive information was exposed to foreign hackers and spies.

The State Department on Friday said that 22 emails on Clinton’s server have been classified as top secret, turning up the pressure on Clinton days before the Iowa caucuses.

A spokesman for Smith, Zachary Kurz, told The National Journal that the chairman was following up on a January hearing on cybersecurity.

“Dur­ing the hear­ing, the chair­man had an ex­change with a private-sec­tor wit­ness who stated un­equi­voc­ally that a fed­er­al of­fi­cial us­ing a private serv­er and email ad­dress as her of­fi­cial gov­ern­ment email risked ex­pos­ing clas­si­fied data and that his com­pany wouldn’t do it be­cause of fed­er­al laws and cy­ber­se­cur­ity guidelines,” Kurz said. “Based on that testi­mony, the chair­man de­term­ined that fur­ther over­sight was ne­ces­sary.”

Smith’s investigation is running parallel with a similar inquiry led by Senate Homeland Security Committee Chairman Ron Johnson Ronald (Ron) Harold JohnsonGOP senator blocks Schumer resolution aimed at Biden probe as tensions run high The Hill's 12:30 Report - Presented by Facebook - Big 10 votes to resume football season GOP votes to authorize subpoenas, depositions in Obama-era probe MORE (R-Wis.). The FBI is also conducting its own investigation.

“Understanding these companies’ roles in providing software and services to maintain former Secretary of State Hillary Clinton’s private email server is critical to improving government cybersecurity standards,” Smith said when launching his investigation.

“A high profile government official deviating from established information security requirements raises significant concerns,” he added.
