Here's CNN's headline: Top Clinton State Department Aide Helped Clinton Foundation

Here's what Cheryl Mills did:

"On June 19, 2012, Mills, then the chief of staff for Clinton at the State Department, boarded a New York City-bound Amtrak train in Washington's Union station.

The next morning, at the offices of a New York based executive search firm, Mills would interview two high-level business executives. Her mission was to help the Clinton Foundation find a new leader, a source told CNN.

According to Mills' attorney, her work for the Clinton Foundation while she was employed at the State Department was strictly voluntary. She received no pay and no government funds were used to finance the short trip."

Cheryl Mills conducted job interviews.
