JACKSON (AP) — Mississippi lawmakers have approved a bill authorizing the construction of a civil rights museum and a history museum.

The bill passed the House and Senate on Monday but was later held for more debate in the Senate.

The proposal had the backing of Republican Gov. Haley Barbour, who’s called it an economic development project. The project had stalled amid debate on private funding.

The Senate wanted to require organizers to secure private donations before any state funding was released for the project. The House balked at the idea.

The bill approved on Monday would provide $20 million for the civil rights structure and $18 million for the Mississippi history museum. The bill states funding for artifacts would be matched with private money.

The bill is House Bill 1463.
