Federal Rules of Criminal Procedure
Rule 18. Place of Prosecution and Trial
Unless a statute or these rules permit otherwise, the government must prosecute an offense in a district where the offense was committed. The court must set the place of trial within the district with due regard for the convenience of the defendant, any victim, and the witnesses, and the prompt administration of justice.
With regard to Hillary Clinton, et alia, all the crimes took place in Washington D.C. or New York City (where the Clinton foundation is located).
Suggesting that Clinton and other senior Democratic executives might be tried in Utah or some other state is beyond silly.
Unless a statute or these rules permit otherwise...
Your reading of Rule 18 is superficial and completely ignores its opening and qualifying phrase. Search the case law and you will find many exceptions in cases of broad criminal conspiracies which allowed prosecution in other eligible federal judicial districts.
Two other facts to consider:
1. The Clinton Foundation, with offices in New York City and Little Rock, is under active investigation by USA Cody Hiland in the Eastern District of Arkansas.
2. American uranium is mined in Nebraska, Texas, Utah and Wyoming and is shipped across many other states; all federal districts involved could be eligible venues for prosecution of a criminal conspiracy involving minerals sold to Uranium One.
Time will tell...
