According to the Washington Post:
"A final 'pre-flight checklist' before the Web site’s Oct. 1 opening, compiled a week before by CMS, shows that 41 of 91 separate functions that CGI was responsible for finishing by the launch were still not working. And a spreadsheet produced by CGI, dated the day of the launch, shows that the company acknowledged about 30 defects on features scheduled to have been working already, including five that it classified as 'critical'".
The question is, what did the President know, and when did he know it? We know the responsible White House staff knew the system would not work because it simply wasn't finished. And that's only for the parts that were to go live on October 1st. As we heard last week from the existing CTO on the project, there is still 30-40% of the backend system that hasn't even been written yet.
I don't think it is reasonable that no one told the President about this. I think the President knew, but decided to push it through anyway. Why? Personally, I think it's because he believed that the glitches would be forgiven, and because the press was behind him, he could always blame the other side, and they would go along as the usually do.
