What does it mean for a bill to be marked up?

When a bill is marked up, it refers to the process by which a legislative committee reviews, amends, and debates the proposed legislation before it is sent to the full legislative body for consideration. During the markup session, committee members can propose changes, add provisions, or delete sections of the bill, resulting in a revised version that reflects their recommendations. This process is crucial for shaping the final content of the bill and ensuring it addresses various concerns before further deliberation.
