True, but that evidence may not be known to the public. It is not uncommon for the FBI to conduct investigations without any public knowledge of any evidence of a crime. In the files on the fourth floor of the J. Edgar Hoover Building, there are records of thousands of investigation carried out in secret by the FBI. Usually if there is insufficient evidence to prosecute after the investigation completes, the bureau will close the investigation with no report to the public. Only in high profile cases, such as the Clinton email investigation does the FBI make a report public.
In high profile investigations such the Russian interference in the election and the Clinton email investigation, there are always leaks creating a media frenzy. Congressional investigations put pressure on the FBI to release information before the investigation is complete which feeds the media frenzy and produces more leaks with both real and false information.
The closest thing we will get to an accurate picture of Russian inference in the election and any Trump campaign involvement will come from the final report of FBI investigation which has now morphed into the investigation by the Special Council. One thing we can count on is that report will not please either side just as the report of the Clinton email investigation brought condemnation from both the right and left.
I think this investigation will show what we already suspect, and that is Trump is not guilty of anything.
Trump was not a politician until he joined this race. And it's not like it's a job he just had to have. For Trump, it was great if he could become President, and if not, he had better things to do anyway.
And again, this Seth Rich story. Why is his computer under lock and key by the authorities? Why did they close the murder investigation? One would think that if the FBI were serious about finding out who hacked the servers, that would be the first place they'd look.
