Maybe it's because without zero evidence of any wrong doing on Trumps part the investigation is still going on? When Hillary Clinton broke a bunch of laws and they had solid evidence of the fact she broke these laws he didnt bring charges against her. How about the fact that Trump campaign was infact spied on and the FBI director lied about it. Then later admitted it but said it was legal surveillance. Comey was corrupt and should have been fired sooner. Only mistake Trump made was waiting for so long.
