In the United States House of Representatives, suspension of the rules is a procedure generally used to quickly pass bills which enjoy broad, bipartisan support.
Most often, bills "on suspension" are non-controversial legislation—such as naming Post Offices of the United States Postal Service or federal buildings.
However, in the 118th Congress, suspension of the rules was often used in order to pass spending bills and continuing resolutions.
Since those bills were negotiated between the Republican-controlled House and the Democratic-controlled Senate, they were generally supported by many members from both parties (allowing them to clear the two-thirds treshold required for suspension of the rules), although they were repeatedly opposed by dozens of fiscally conservative Republicans.
Due to a procedural glitch, the bill was improperly sent to the President and in an unusual attempt to solve the problem, the House passed it again as H.R. 6124.
