Even if Hillary Clinton does not win the presidency on Tuesday, Republicans on Capitol Hill say they are revving up for more investigations involving the former secretary of state.

House Oversight Committee members remain unconvinced that charges of impropriety against Clinton have been fully reviewed.

Chairman Jason Chaffetz also wants to know if the FBI's deputy director, Andrew McCabe, whose wife received $675,000 in political donations from a close friend of the Clintons, is still working on the Clinton email case in light of that disclosure.

House Oversight Committee Chairman Jason Chaffetz wants to know if the FBI's deputy director, Andrew McCabe, left, whose wife Jill, right, received $675,000 in political donations from a close friend of the Clintons, is still working on the Clinton email case in light of that disclosure

McCabe's wife Jill ran for a Virginia state senate seat in 2015. She lost the race, but it wasn't for lack of resources. Virginia Governor Terry McAuliffe's political action committee, Common Good VA, and the state Democratic Party poured money into her race last fall.

McAuliffe's PAC gave McCabe $467,000. The Democratic Party of Virginia spent another $207,788 on her.

'It seems like an obscene amount of money for a losing race,' Chaffetz told the Washington Post.

A month before Common Good VA made its first donation Hillary Clinton headlined a fundraiser for the group with McAuliffe, a longtime friend, aide and Clinton Foundation board member.

The FBI seized Clinton's server soon after, beginning it's yearlong investigation into her emails that concluded this past July only to restart last week amid the discovery of new messages on a top Clinton staffers's estranged husband's computer.

Chaffetz sent McCabe a letter last Thursday demanding documentation of the ethical guidance that the FBI agent sought and received from the bureau before his wife announced her candidacy.

He also asked McCabe to state for the record when he found out about the FBI's investigation into Clinton.

McCabe was only promoted to a role where he would have oversight in the the Clinton case in February, months after his wife lost the Virginia senate seat, prompting questions of what he knew and when.

Chaffetz asked for a response by Nov. 10.

He did not ask McCabe to recuse himself from the case at that time. The letter was sent a day before FBI director James Comey told Congress the bureau had new information that could be 'pertinent' to Clinton's case that it was pursuing.
