Hillary Clinton will attend a private fundraiser Tuesday at the Chicago home of Rajiv Fernando, a Democratic campaign bundler who once enjoyed a prestigious State Department appointment under Clinton before resigning amid controversy about his qualifications.

Scott Parker, the Republican National Committee's director of investigations, filed a Freedom of Information Act request Monday with the Office of Government Ethics for any records that might have mentioned the potential conflict of interest created by Fernando's appointment.

Fernando has given between $500,000 and $1 million to the Clinton Foundation. He was also a top bundler for President Obama's presidential campaigns.

In 2011, Clinton appointed Fernando to the International Security Advisory Board, an elite panel of scientific and technical security experts tasked with advising the secretary on arms control and proliferation, among other issues.

Members of the board included Douglas Bereuter, a former congressman, and David Kay, the former chief weapons inspector at the United Nations.

The appointment sparked controversy after critics questioned Fernando's complete lack of intelligence credentials.

Critics accused Clinton and Obama of selecting Fernando for the prestigious post as a reward for the money he had raised.

Fernando quietly stepped down from the board just days after ABC News asked the State Department why the financial trader was included among the group of international security experts.

His securities trading firm, Chopper Trading, was recently acquired by the larger DRW Trading Group.

Supporters who attend Fernando's fundraising event Tuesday must pay $2,700 to get in the door. Donors who raise $27,000 will be named "co-hosts" and those who contribute $50,000 or more will be named "event hosts," according to Crain's Chicago Business.

In addition to the RNC's FOIA request, conservative watchdog Citizens United has filed a records request with the State Department for correspondence between Fernando and top agency officials.

Citizens United sued the State Department after it stonewalled the FOIA request for emails and memos concerning Fernando's controversial appointment.

The State Department will be forced to begin producing those documents on a rolling basis at the end of August.
