Common sense should tell objective observers that the FBI would have NEVER reopened this case if the evidence wasn't significant and Comey knew he would have been under attack for withholding this new evidence until after the election was most assuredly the motivation to release it now.
More likely he found something tangentially related to his initial investigation (ex. emails that went through Clinton's private server) and was duty bound to report it to the House committee.
In the end, probably nothing of significance. Why would Hillary be discussing national security issues with her personal aide?
Also, what kind of an idiot uses their wife's laptop to sext people?
