While serving on the board of Boeing in 2020, GOP presidential candidate and former South Carolina governor Nikki Haley helped kill an initiative designed to force the company to more comprehensively disclose its spending to influence politicians and safety regulators, government filings show.

The Boeing board’s opposition to the shareholder measure came the same year that the company was lobbying the Federal Aviation Administration on “certification,” or approving planes to fly — and the agency lifted its grounding order of the company’s 737 fleet, which had been in effect since two of the airliners had crashed in 2018 and 2019, killing 346 people.

Haley was a member of Boeing’s board when it unanimously opposed shareholders’ transparency proposal, which proponents said was designed to uncover whether Boeing had bought itself regulatory relief from federal safety officials.
