They’ve done six background checks on him already without finding a crime, so why would they expect to find anything now?
And since we know that FBI agents, and employees can be liberals, and take whatever action they deem necessary to get to a specific end, it's likely that there were some liberal agents involved with all these six backgrounds. If anything untoward had been out there, the Dems, and those agents would have found it.
actually if they were to find one now wouldn’t that say the other six were failures... not sure the FBI wants anymore PR!
