Andrew McCabe has long been a controversial figure at the FBI. His position as Deputy Director of the FBI came under intense scrutiny during the Clinton email investigation after it came to light that his wife, Jill McCabe, took nearly $500,000 from Virginia Governor Terry McAuliffe to fund her Senate campaign.

But sure, no reason to be wary the McCabe was put in charge of supervising that particular investigation.
