One of Hillary Clinton’s top State Department aides participated in high-level recruiting for the Clinton Foundation while she worked for the government, according to CNN. The report raises further questions about interactions between people who worked for the two organizations while Clinton was secretary of State.

In 2012, Clinton’s then-chief of staff, Cheryl Mills, traveled to New York to interview candidates for a top job at the Clinton Foundation, CNN found.

The report comes just days after new Clinton emails were revealed, including one where an aide to Bill Clinton inquired about a meeting for a Clinton Foundation donor.

Donald Trump and the Republican National Committee have jumped on the emails, saying they’re examples of “pay-to-play relationships.”

On Wednesday, Republican National Committee Chairman Reince Priebus demanded that State release the rest of the emails that have been withheld from the public.

“If the State Department continues to withhold these emails, Hillary Clinton should demand they be released, or release them herself,” Priebus said in a statement. “Anything less than a full release of these public records before voting begins will only further prove that we have a rigged system that has one set of rules political elites and another for everyone else.”

And on Thursday, the Trump campaign sent an email to supporters saying the emails “exposed a concerning link between the Clinton Foundation and the State Department!”

The message asked people to sign a petition “to the Department of Justice demanding that they launch an investigation into the scandal-plagued Clinton Foundation.”

Meanwhile, the Clinton campaign has denied that there is any inappropriate overlap, saying Mills' work was voluntary.

"Cheryl volunteered her personal time to a charitable organization, as she has to other charities," spokesman Brian Fallon told CNN. "Cheryl paid for her travel to New York City personally, and it was crystal clear to all involved that this had nothing to do with her official duties. The idea that this poses a conflict of interest is absurd."

The State Department told CNN that federal employees could engage in personal activities as long as they followed ethics codes.
