[I've been told the answer is "Yes," by an authoritative source, although YMMV because numbers do change. Welcome, Wonkette readers. Welcome, Raw Story readers.

See The White House Phone Directory (May 18, 2007). Because I figure the regular switchboard might be busy tomorrow, but if you've got the White House phone directory, you can just work your way down until somebody picks up. (Actually, in the spirit of CD interviewing people, it might be more interesting and fun to say "Hi! I write for ______________. Do you think that Libby's commuted sentence involved obstruction of justice? Why or why not?")

Most of the numbers in the Directory match what I've been able to glean from open sources, so it looks authentic. The offices are taken from the White House site, and the numbers are formatted like so: 1-202-555-1212 / 1-202-555-1212, where the first number is via internet search, and the second, italic number is from the Directory:

What they have never, that I've seen anyway, made note of is that Abramoff had his own plant right in the heart of the White House. His former "aide" Susan Ralston, who has been Karl Rove's right-hand woman for most if not the entire BushCo presidency reign of terror. Read more…
