Public affairs and strategy shop Mercury is providing Capitol Hill support for online lodging marketplace AirBnB on a series of economic development issues.

AirBnBThe Omnicom public affairs unit is charged with aiding AirBnB in Washington on issues related to antitrust, as well as judiciary and e-commerce matters.

San Francisco-based AirBnB, which now maintains 19 offices worldwide, is currently valued at around $25 billion, and posted projected revenues of $900 million for 2015. The property rental resource, which has faced legal pressure in some cities on the grounds of safety and tenant leasing regulations, as well as pushback from the hotel lobby with which it competes, in August hired political consultant and crisis communications expert Chris Lehane, a top Clinton administration advisor who also served as spokesperson for Al Gore's 2000 presidential bid, to serve as chief of head of global policy and public affairs.

The airbnb account will be managed by Mercury partner Vin Weber, who was previously Republican Congressman of Minnesota.
