Ottawa, the capitol of Canada

The correct word here would have been "capital", which, as a noun, can mean (1) a city that is the seat of the government for a country or state, or (2) an amount of money or property; and, as an adjective, can mean (1) an uppercase letter, (2) first rate, excellent, or (3) main, principal.

Capitol, on the other hand, is the (actual) building where U.S. Congress meets.  Its white dome is depicted in the logo of record label Capital Records -- and that's about where its usage ends.  Perhaps because of its association with the U.S. capital, the two words are often confused.  They may even have the same roots, but capitol is derived from Latin Capitolium, temple of Jupiter Optimus Maximus on the Capitoline Hill in ancient Rome (which probably looked nothing like the United States Capitol does today).

Maybe the senate reference left the Star writer in a Roman state of mind!
