Emling will be joining Citigroup's global government affairs office, where he will be one of two heads for the federal legislative affairs team. He replaces Robert Schellhas, who formerly ran the department without a co-head and left the company in May to become a principal at Ernst & Young.
Emling is expected to play a key role in Citigroup's public affairs efforts during a period when federal regulators are crafting new rules and guidelines for the financial services sector.
Emling, a former Bush administration Treasury official, and his soon-to-be chosen partner, will report to Candi Wolff, executive VP of global government affairs. The five members of the federal legislative affairs office will report to Emling.
Inquiries regarding Emling's addition to Citigroup were referred back to an offical statement from Wolff: "John brings years of experience and expertise in financial services and consumer issues as well as a wealth of experience on Capitol Hill and the executive branch. He will be a great addition to the team and we look forward to his leadership on federal legislative issues."
Emling previously worked with Wolff from 2005 to 2007 while she was the chief lobbyist for President George W. Bush.
In February, Citigroup hired Sean Kevelighan as head of communications and public affairs for its North American consumer banking business. Kevelighan formerly served as press secretary for the White House's Office of Management and Budget, and as a spokesperson for the Treasury Department.
Citigroup isn't the only financial company bolstering its communications staff: JPMorgan Chase has confirmed hiring Weber Shandwick's Melissa Shuffield as VP of communications and corporate affairs.
