After Hillary Clinton admitted to using a private email address during her time as Secretary of State, an investigation was launched to find out why she used a private account and what was discussed.

Since the email controversy, 29 percent of Americans say their opinion of the former first lady has worsened, according to CBS News.

Yet, 65 percent say their opinion of the most likely presidential candidate in 2016 has remained the same.

In the same poll, 49 percent of Republicans say their opinion of Clinton is worse, and 28 percent of independents say the same thing about her.

Twenty-six percent of Americans have actually gotten a more favorable view of Hillary Clinton after news of the email scandal.

Her favorable views are 12 points lower than they were in fall 2013 after she left the position as secretary of state. Most Democrats continue to hold favorable views of Clinton, but the percentage has dropped by eight points.

The percentage of views that are undecided has risen by eight points.

Back in 2009, when Clinton was still Secretary of State, a CBS News polling recorded 58 percent of Americans viewed her favorably.

After reports about the email scandal, the public gives Clinton her most negative marks on honesty but say she is best at leadership and empathy.

Meanwhile, the conservative group Freedom Watch has filed a lawsuit against Clinton citing that she failed to produce documents under the Freedom of Information Act, The Hill reports.

The conservative group filed the civil suit Wednesday alleging that Clinton withheld documents under FOIA regarding Department waivers given to people conducting business with Iran during her tenure.

The complaint says that the Clinton Foundation sold access to other U.S. government officials in return for donations to the organization and concealed the information by using a private computer server for Hillary Clinton's emails.
