Primary Takeaway

Stated simply, the primary takeaway from the past 250 years of recorded American history is that Presidents are not kings.  To make the point as plain as possible, it is clear to this Court for the reasons explained above that, with respect to senior-level presidential aides, absolute immunity from compelled congressional process simply does not exist.

[T]his Court holds that individuals who have been subpoenaed for testimony by an authorized committee of Congress must appear for testimony in response to that subpoena -- i.e., they cannot ignore or defy congressional compulsory process, by order of the President or otherwise.
