The second Amendment, proposed at Federal Hall in New York City but not ratified until about 203 years later in 1992 as the 27th amendment, had to do with Congress not being able to give itself a raise in pay without its constituents having the ability to disapprove. The increase in pay goes into effect after the following House of Representatives election.
Here’s the wording:
“No law, varying the compensation for the services of the Senators and Representatives, shall take effect, until an election of Representatives shall have intervened.”
