They are all braying that sort of nonsense. Prove his innocence... Just because we didn't find proof of wrongdoing doesn't mean it didn't occur...
Far from American Jurisprudence, it reeks of the mentality seen in Salem.
Throw her in! If she floats, she's a witch!
The principle of presumed innocence, of being guilty beyond a reasonable doubt does not mean "beyond reason", and the Democrats are.
Perhaps they are counting on the ignorance of Americans as to their own Rights, or that those same Rights extend to the POTUS, as well as the most indigent of us all, to any Citizen accused of any crime in the United States.
These same Rights, including that presumption of innocence, are (by demand by Democrats) applied even to foreign agents working on these shores.
