-- Hillary Clinton isn't the only official who uses a non-government email address.
A business card obtained by ABC News shows that Rep. Jason Chaffetz, R-Utah, lists his Gmail address on his official House card.
After it was revealed on Tuesday that former Secretary of State Hillary Clinton conducted all of her government business from personal email accounts, personal email has been the topic du jour, and Chaffetz is at the forefront.
Chaffetz, who chairs the House Oversight and Government Reform Committee, announced Tuesday that his panel would join in an investigation of Clinton's email use.
"Violations of the Federal Records Act within federal agencies is something we take very seriously," Chaffetz said Tuesday in a statement. "The House Oversight Committee will work with [Rep. Trey] Gowdy and the Select Committee on Benghazi to further explore Hillary Clinton's use of personal emails while at the State Department."
Chaffetz told ABC News that his business card was not paid for with government funds and that Congress is not subject to the Federal Records Act. He said that he uses both a Gmail account and a government email account.
