Kevin Varney, chief of staff at the Export-Import Bank for Obama’s first term, joined Boeing as a director this month, according to his LinkedIn page.

Boeing is by far the largest recipient of Export-Import Bank subsidies — typically benefitting from about 40 percent of all Ex-Im financing. The charter for Ex-Im, a federal agency often called “Boeing’s Bank,” will expire at the end of June unless Congress renews it. Conservatives are fighting to let the Bank die. Boeing — along with the Chamber of Commerce, the National Association of Manufacturers, and some bank lobbyists — is leading the charge for reauthorization.
