At an NBC "commander-in-chief" forum Wednesday, the Democratic nominee stressed that her 2002 vote was a mistake and said it was important to learn from it. She also asked to be judged on her entire record and argued that Republican Donald Trump had also voiced support for the war at the time, but "refuses to take responsibility."

Hillary Clinton is trying to assure voters that she was careful in her handling of classified information as secretary of state.

Clinton says, "I did exactly what I should have done and I take it very seriously. Always have, always will."

Clinton was asked by a veteran during a "commander in chief forum" hosted by NBC how she could be trusted, given her use of a private email server as secretary of state.

Clinton insists she never used an insecure system to handle classified material designated and marked with clear headers.

She says that she "communicated about classified material on a wholly separate system" and "took it very seriously."

Democrat Hillary Clinton says none of the emails she sent or received had a header that clearly marked "top secret."

The former secretary of state addressed her use of private email during a forum Wednesday night on NBC.

She noted that she has years of experience dealing with classified material dating back to her time as a senator. Classified material usually has a heading marked "top secret," she said.

She insisted that none of the messages sent or received on her private server had such a heading.

Clinton conceded that some of the messages included references to the covert drone program. But she said there was no discussion of "covert actions" that were being considered in the messages.

She also said there was no evidence her email server was hacked.
