FBI Deputy Director Andrew McCabe's involvement in the Hillary Clinton investigation is being questioned by the chairman of the U.S. House of Representatives Oversight committee.

"News accounts have raised questions about a potential conflict of interest related to donations from the political action committee of Virginia Governor Terry McAuliffe, a longtime fundraiser for the Clintons, to the state Senate campaign of your wife, Dr. Jill McCabe," Rep. Jason Chaffetz, R-Utah, wrote Thursday to McCabe.

To address those questions, Chaffetz is asking McCabe to turn over documents and answer the following questions:



• Turn in all documents relating to the ethics guidance received from the FBI regarding his wife’s campaign

• Give the date he became aware the State Department was pressuring the FBI to reverse its decision regarding the classification of one of Clinton’s emails

• Provide information on whether he had any contact with the State Department regarding the classifications of Clinton’s emails

• Provide the date he first became aware the FBI had opened an investigation intolinton’s email server

• Whether he was present for any briefings while he was associate deputy director

• Whether the personnel office in the Washington Field Office provided any support to the investigation prior to his promotion

McCabe, who the FBI said assumed an oversight role into the investigation of Clinton's handling of classified information on a private email server on Feb. 1 of this year when he was promoted to his recent position, is married to Jill McCabe. She ran for a Senate seat in Virginia in 2015 and her campaign received $450,000 in donations from McAuliffe’s PAC, Common Good VA, in addition to another $207,788 from the Democratic Party of Virginia that Chaffetz said was also raised by McAuliffe following a June 2015 fundraiser headlined by Clinton.

"Some of the money raised from Clinton associates, such as Doug Band and Robert Johnson, was donated prior to the commencement of the FBI’s investigation (into Clinton)," wrote Chaffetz. "However, a significant amount was donated after the FBI had initiated its investigation and begun a meeting with Secretary Clinton's attorneys in August 2015."
