clarkClark Stevens, assistant secretary of public affairs at the US Department of Homeland Security, has decamped for Airbnb in a new post overseeing safety initiatives.

Stevens takes the title of global head of strategic safety initiatives at Airbnb, as the San Francisco company tackles challenges on the legal, regulatory and safety front from the hotel industry and cities where it operates.

Stevens worked on the Obama presidential campaign in Virginia and took a press secretary post at the Federal Emergency Management Agency in 2009. He spent two years at Homeland Security around two and a half years stationed at the White House as an assistant press secretary. He earlier worked on the agency front at Fenton Communications.

Airbnb critics often cite security concerns as a key sticking point against the service, which allows house and apartment owners to rent out their properties on a nightly basis. A New York condo owner whose board has banned Airbnb argued in the New York Post Nov. 23 that the company's business model is a form of piracy that allows apartments to be rented to a "burglar or a pedophile … without questions asked."
