Before I start, am not saying POTUS did anything wrong with his taxes. Having said that, if he was approached by a Q delegation prior to joining the plan, it seems that the level of planning we've seen would also make sure that if POTUS would include making sure his taxes were prepared to be especially tippy top for at least 7 years prior to running for office.

In the US, we are expected to retain our previous tax records going back 7 years, in the event that we were audited for the current year.

As I understand things, could be wrong but isn't even the Internal Revenue Service required to have some probable cause to start a more expansive investigation into prior tax declarations?

Can Congress use some mere allegation of collusion to gain access to POTUS's taxes if the IRS is not able to absent some irregularity? And, wouldn't the SC already have had some authority to review them? Nothing there, or some IRS investigation would have happened under Hussein is my guess.
