Anyone that thinks this has any chance of success have not been paying attention since 2017. Attempts to put Trump in jail fail. FBI failed twice, trying another time. Mueller failed once. Senate failed once. Steele (MI6) failed once, and numerous similar probes like AG is doing failed too. Anyone with even a tiny knowledge of US political system know that past presidents (or presidential candidates) don't go to jail, even if they did criminal acts.
But, hey! Maybe this will be the second investigation into him that won't end up either faking information (Steele, FBI), or using the before mentioned fake information (Mueller)
