Briefing Sections
Section 1
Funding authority lapses
When an appropriations deadline passes without new funding, agencies covered by the lapse must begin shutdown procedures under federal fiscal law.
Section 2
Agencies separate exempt and non-exempt operations
Functions tied to safety of life, protection of property, and some constitutional duties continue, while many other activities pause or operate with reduced staffing.
Section 3
Federal workers are furloughed or required to work without immediate pay
Some employees are furloughed, while others remain on duty because their work is legally excepted. Congress usually addresses back pay separately.
Section 4
Congress and the president must enact funding to end the shutdown
The shutdown ends only when Congress passes and the president signs an appropriations bill or continuing resolution restoring funding.
