The chairman of the U.S. Export-Import Bank has spent a lot of time on Capitol Hill lately fighting to save his embattled institution. The bank, whose charter lapses June 30, has been the target of a coordinated campaign orchestrated by conservatives who call it a form of crony capitalism. Which means chairman Fred Hochberg has been shuttling between meetings with influential lawmakers, pleading with top House Republicans like Majority Leader Kevin McCarthy and Financial Services Chairman Jeb Hensarling to keep the credit export agency alive. “I’m still confident that we are going to get reauthorized,” Hochberg told reporters Friday at a breakfast hosted by the Christian Science Monitor.
