try to freelance your way into a White House press conference and see what happens.
like I said COULD fall under, depends on the jurisdiction.
there has been a case or two of "obtaining by false pretenses" for what you suggested, prosecuted under some local law in a local (county) jurisdiction.
as always, if you want legal advice, see a lawyer.
You camparing the White House to some local PD?

Apples and oranges.
If you walked in and gave your real name and asked for something you need for an independent publication (even a web page, web posting or blog, etc.) , there is nothing false about it.
