Gov. Nikki Haley and state officials have joined hundreds of Boeing workers in North Charleston to cut the ribbon opening the company's 787 jetliner assembly plant at the center of a National Labor Relations Board dispute.

Haley on Friday called Boeing a great American company said its workers make all South Carolinians proud.

The plant is the target of an NLRB complaint claiming that Boeing built the plant in South Carolina, a right-to-work state, because it was concerned about strikes by union workers in Washington state. Referencing the lawsuit, U.S. Sen. Lindsey Graham got loud cheers from the crowd when he said Boeing is here to stay in South Carolina.

The $750 million plant represents the largest single industrial investment in South Carolina history.
