No.
Larry Sinclair was under oath in his affidavit, and had gay bar name, taxi service, and a highly believable story. I think we are not shocked that our president is a little gay, nor that he is all about himself. I might have had trouble with believing the cocaine but it was so highly specific. If Sinclair made that up, he might have had them both sniffing it. But he puts Barack getting crack for himself, and smoking it from a little crack pipe our IL senator kept in his pocket.
Sinclair met Obama by telling his middle eastern limo driver he’d like to find someone to “show him the town,” and the driver knew just what he meant. Went to the gay bar and came out with Obama, who apparently was happy to cruise around with this white out of towner! Like a girl down at the docks!
