It’s the continued investigation sparked by the personal email account used by then-Secretary of State Hillary Clinton, receiving classified information.

“We’ve well been warned about how hackers can get into private email accounts and all,” said Rep. Andy Harris, (R) Maryland. “I was surprised that the secretary would ever consider using a private email account.”

Congressman Andy Harris of Maryland says the matter and continuous investigations are about more than emails.

“Why four Americans died there under the secretary’s watch. Now, there were other people involved, we just want to get to the bottom. How could something have gone so terribly wrong?” said Harris.

Hillary Clinton will testify Thursday in Washington, D.C. It’s been three years, seven investigations and thousands of pages of emails since the Benghazi attack.

“I think it’s a sad day for all of us because we made a commitment to the families. The families came in with tears in their eyes, literally, and said, ‘Please do not make this a political football.’ That’s exactly what’s happened,” said Rep. Elijah Cummings, (D) Maryland.

On CBS Face the Nation Sunday, Maryland Congressman Elijah Cummings says the continued investigations are stirring away from making sure what happened doesn’t happen again, focusing more on politics.

“I respect Mr. Cummings, the ranking member, but the fact of the matter is that he is one who’s made this highly political from the very beginning,” said Rep. Harris.

“What can we do to make things better in the future? That’s what this is all about,” Rep. Cummings said.
