A once-obscure 1996 statute lets Congress kill a federal rule in an afternoon, bypassing the filibuster entirely. Only 20 of 461 attempts have become law since it took effect.

Congress built a 45-day clock into federal law so it always gets a vote on canceling its own spending. The Trump administration found a way to run out that clock instead.

A pocket rescission lets a president freeze spending until it legally expires, no vote required. The GAO says it's illegal. The current OMB director wants to use it anyway.
