The government watchdog group Judicial Watch announced Friday it will take the FBI to court in an effort to obtain documents related to campaign donations made to the wife of FBI Deputy Director Andrew McCabe.

For most Freedom of Information Act lawsuits brought by Judicial Watch, that same group is also the party that filed the original FOIA request. In this instance, however, Judicial Watch is representing Jeffrey A. Danik, a retired FBI agent.

Danik asked for a host of documents that, if they exist, would be related to political donations that were made to Jill McCabe's run for a Virginia state senate seat in 2015. For that campaign, McCabe received over $500,000 from a political action committee run by Virginia Governor Terry McAuliffe, a long-time ally of the Clintons.

The donations have been a source of scrutiny because at the time, Andrew McCabe was overseeing the FBI's field office in Washington, D.C., meaning he had some oversight of the Hillary Clinton email investigation.

Pundits openly wondered if the heavy donations by a PAC backed by McAuliffe, a Clinton ally, to a small Senate race could have ethically compromised Mr. McCabe, or been part of some kind of quid pro quo.

"I am saddened by how the FBI's reputation has been tarnished by the poor judgment and ethics of its leadership," Mr. Danik said in a press release by Judicial Watch. "I know I'm not the only retired (or serving) FBI special agent who is concerned about Mr. McCabe's conflicts of interest on the Clinton email matter. The agency seems to be illegally hiding records about this scandal, which is why I'm heading to court with Judicial Watch."

Apart from representing Danik in this particular request, Judicial Watch also filed three other lawsuits against the FBI in July, all of them related to McCabe and his wife's political campaign.
