Sorry, it's not. It was originally developed in Finland by Linus Torvalds, the son of a well-known communist.
Somehow I doubt it's (the White House) running on Red Flag.
Well let's hope it's not Red Flag, but even if it's not, they still have the same open source parent code, which is free for anyone on the internet to download and examine the source code text base for security flaws.
Thankfully it only seems to be a public site, and not any sort of intranet (which I highly doubt has very much Linux on it at all).
Thank God you're wrong.
And on a related note:

Which is precisely why Linux is secure, for reasons similar to why the strongest cryptographic algorithms are freely available for review. "Black box" security is no kind of security, boxes are meant to be opened.
