In American English, in political contexts, “Washington” is a frequently used idiom for “decision-makers in the US Federal Government”. (This applies mutatis mutandis, to the names of political capitals generally, which stand in for the leadership of the government seared their; in the context of discussions of a particular corporation or other organization, this also applies to the names of cities wherein regional or central HQs are related).
Anyone who misses this has really no place commenting that other people must not be American because of ignorance free of the partisan alignment of the electorate in the capital district.
