Washington, D.C.—Campaign finance watchdog Public Campaign Action Fund is requesting Delta Airlines disclose the perks they provide state officials in places where they do business, concerned about the undue influence the company could be building with elected officials.

According to the letter:

Washington, D.C.—Public Campaign Action Fund sent letters to 20 members of Congress today requesting full disclosure of any benefits they’ve received from Delta Air Lines as Congress considers the long-term Federal Aviation Administration reauthorization legislation.  Delta Air Lines has continued to lobby Republican leadership to include an unrelated  controversial union-busting provision in the legislation to benefit the company.

All 20 have received campaign contributions from Delta’s political action committee (PAC) or employees during their time in Congress.
