A manner or way of speaking, vernacular, idiom, as in legal parlance.
Every president after Jefferson has professed agreement with Jefferson’s concept that the freedom of the American press to print its versions of the facts, background and likely consequences of human events was a constitutional principle permanently reserved from any form of interference by government. Consequently Jefferson denounced … either direct or indirect attempts by government to do what in current parlance has become known as “management of the news.”
