Chelsea is waiting in the wings with those files. She's evil squared.
Before political office became a lifetime appointment, those files would be long out of date and useless as politicians retire and move on. But even with the average politician spending a 100 years in office, the files have to be losing their 'threat value'. As the old congressmen retire and pass away, it gets to the point of, 'Who cares?' Who cares what some retired or dead congressman did in 1975?
All the dirt Hillary has on Congress is aging rapidly. She did steal FBI files, but that was in the early 90s. And the dirt they contained was in the 70s-80s. Like Obama before her, had she become President all the three letter government agencies, NSA/FBI/IRS/HLS/ATF and all of them, would have been converted into her own personal 'secret police force'. However, by the grace of God that did not happen. So now, what does she have, really?
Eventually Hillary will face a 'put up or shut up' moment. And by the time Chelsea becomes an issue, all that so called 'dirt' will be meaningless.
