WASHINGTON, Feb. 27 — Democrats in Congress are pushing to extend union protection to 43,000 federal airport security workers, reviving a debate that stalled the creation of the Department of Homeland Security and could now derail broad antiterrorism legislation.

The proposal has provoked opposition from Senate Republicans and the Bush administration. It is the latest in a series of labor-related fights in Washington as Democrats try to use their new majority to push long-delayed proposals that benefit rank-and-file workers, like increasing the minimum wage.
