Virginia Governor Terry McAuliffe, one of Bill and Hillary Clinton's most consistent backers, donated nearly $500,000 to the Virginia state Senate campaign of a candidate who is married to the FBI's deputy director.

A PAC McAuliffe's controls donated $467,500 to the 2015 state Senate campaign of Dr. Jill McCabe, part of McAuliffe's ill-fated plan to try to take control of the Virginia Senate.

The donations poured in just a few months after McCabe launched her Senate campaign in March 2015, the Wall Street Journal reported.

McCabe's husband, Andrew McCabe, ran the bureau's Washington field office, which in July 2015 launched an investigation into Clinton's email practices.

Virginia Governor Terry McAulifee, who spoke at the Democratic convention in Philadelphia, had his PAC donate $500,000 to a state senate candidate whose husband, Andrew McAbe, is now the number two official at the FBI

Dr. Jill McCabe didn't win her race for the state Senate, but got a big assist from Governor Terry McAuliffe, whose PAC kicked in $500,000

The state Democratic Party also donated $208,000 to Jill McCabe's campaign, which ultimately was unsuccessful.

McAuliffe's is one of the closest backers of the Clintons, having been Bill Clinton's top fundraiser. Both Clintons backed McAuliffe in his campaign to capture the governorship.

In a statement posted Sunday night, the FBI said McCabe 'played no role, attended no events, and did not participate in fundraising or support of any kind. Months after the completion of her campaign, then-Associate Deputy Director McCabe was promoted to Deputy, where, in that position, he assumed for the first time, an oversight role in the investigation into Secretary Clinton's emails.'

According to a further statement Monday: 'When Jill McCabe first considered running for the state Senate seat, ADIC McCabe consulted with top FBI headquarters and field office ethics officers for guidance, including briefings on the Hatch Act, to prevent against any actual or potential conflict-of-interest, in the event she decided to go forward.'

According to the bureau 'When she chose to run, ADIC McCabe and FBI lawyers implemented a system of recusal from all FBI investigative matters involving Virginia politics, a process followed for the remainder of her campaign.'

During the campaign, he played no role, attended no events, and did not participate in fundraising or support of any kind. Months after the completion of her campaign, then-Associate Deputy Director McCabe was promoted to Deputy, where, in that position, he assumed for the first time, an oversight role in the investigation into Secretary Clinton's emails.'

Andrew McCabe rose to become deputy director of the FBI. Virginia Governor Terry McAuliffe, a key ally of Bill and Hillary Clinton, had a PAC donate $500,000 to McCabe's wife's state Senate campaign. McCabe was promoted following to the bureau's director, James Comey's (right) decision not to recommend charges against Hillary Clinton

Dr. McAbe's office said there was no conflict because her husband was not involved in her campaign in any way. He didn't take over his position, which would have provided authority over the investigation, until her race was over.

'Once I decided to run, my husband had no formal role in my campaign other than to be a supportive husband to me and our children,' she told the paper. 'As a federal official ... everyone who participated in our campaign understood and respected that he could not participate.'

Jill McAbe is a physician who hadn't run for office before. Her campaign effort spent $1.8 million on her unsuccessful effort. McAuliffe was working to help Democrats take over the state Senate, which had been working to stymie his efforts.
