Who are "they," and when did they make this demand?
‘they’ were the drive-by media in the spring of 2008... Abc, CBS, NBC, CNN, cnbc, etc. They started that once it became obvious he was going to win the GOP nomination
After McCain handed over the info, and he was ruled as eligible, the furor died down around April timeframe. In June 2008, they asked 0bama for the same information, once it was clear he would have the nomination. He has not complied to the request yet... And has a spent $2.9m to keep people from getting the information
Really, a 10 second google could have answered the question
