The D.C. Council unanimously approved a bill in a second full council vote that aims to restrict political contributions by government contractors doing business with the district.

The bill also addresses improper coordination between campaigns, political action committees and independent expenditure committees.

The pay-to-play component of the bill would ban campaign contributions by businesses seeking contracts of $250,000 or more.

Provided the mayor approves the legislation, the act of the council travels to Congress for a 30-day review. If approved and funded, the bill would take effect on October 1, 2019.

Pay-to-play provisions would take effect after the November 2020 general election.
