The FBI has been investigating Hillary Clinton's use of a private e-mail server while secretary of State in order to determine whether she mishandled classified information, with some reports suggesting the Democratic presidential front-runner may be indicted. Most voters still believe it’s likely Clinton broke the law by sending and receiving classified information through the server, but they are far less convinced that serious charges will be brought against her.

A new Rasmussen Reports national telephone survey finds that 64% of Likely U.S. Voters now think it’s likely Clinton broke the law by sending and receiving e-mails containing classified information through a private e-mail server while serving as secretary of State. That’s up from 59% in September and includes 47% who say it's Very Likely. Twenty-nine percent (29%) consider it unlikely that Clinton broke the law, although only nine percent (9%) say it’s Not At All Likely. (To see survey question wording, click here.)

The survey of 1,000 Likely Voters was conducted on January 24-25, 2016 by Rasmussen Reports. The margin of sampling error is +/- 3 percentage points with a 95% level of confidence. Field work for all Rasmussen Reports surveys is conducted by Pulse Opinion Research, LLC. See methodology.
