@revelette1,
We may be conflating two very different "Clinton" investigations, i.e. the original Starr report regarding President Bill Clinton and the subsequent investigation of SECSTATE Hillary Clinton's handling of classified material on a private server ( something expressly forbidden by law) In the latter case the investigation was done nominally by the Justice Department, and while no closure report was issued by the AG Loretta Lynch, FBI Director Comey exonerated her in a rather vague and ambiguous way, later reopeneing the investigation and ended it without formal closure.
The second Clinton investigation is more related to the recently completed Mueller investigation of Trump in that both involved then opposing candidates for the presidency, both were staffed by largely the same core of FBI and Justice Dept. officials, and both yielded no criminal findings on the targets of the investigations. The Hillary investigation was done rather quickly and informally =, while the second took almost two years and involved very formal and rigorous methods, including unannounced FBI raids on the homes and offices of potential witnesses. This was in stark contrast to the Hillary investigation in which most of the key witnesses were treated as legal counsel for the target, and therefore somewhat immune to questioning, and the computers & servers involved were left in the hands of the targeted people and were subsequently destroyed by them along with thousands of unexamined files. No detsailed report of the evidence and findings in the Hillary investigation was ever published.
