Howard Dean, MD, speculated that Donald Trump's recurrent snorting during the First Presidential Debate might be secondary to cocaine use. Potentially correct speculation without real evidence. President Obama not being a citizen of the USA as cultivated by the Donald for years was potentially correct without real evidence. So Donald, as President Obama responded, it is your obligation as a Presidential candidate to provide the nation with documented lab results from drug screening of your blood and urine. Don't need to test your crap...we already know it is BS!
