This so-called charity lists two addresses, one of which turns out to be a post office box at a UPS location in Alexandria, Virginia. The physical address in the IRS filing is occupied by a drug and alcohol recovery service, and has been for "a couple of years" according to its receptionist, which extends back to the date listed on the IRS filing of May 2011. Nobody at that recovery service has ever heard of the Barack H Obama Foundation.
