Why it matters: Multiple fights between the two branches of government will wind through the courts, with some likely to end up at the Supreme Court.

An outside adviser to the West Wing tells Axios: "Trump’s statement that they will not comply with the subpoenas and document requests was not posturing or an opening negotiating position. It is administration policy."
