In the wake of the occupation of the Malheur National Wildlife Refuge in Burns, Oregon, the Spokane County sheriff says his officers are encountering more people who claim to be "sovereign citizens" who don't need a driver's license.

Sheriff Ozzie Knezovich says the lengthy standoff at an Oregon wildlife refuge seems to have brought such people out of the woodwork.

Spokane County deputies have dealt with two people in the past week who claimed to be a "traveler" or "free traveler," and said that, according to the U.S. Constitution, they didn't have to have a license.

The Spokesman-Review says numerous websites contend a license is only required if someone is using the highway for commerce.

Knezovich says state law says no person may drive any motor vehicle upon a highway unless the person has a valid driver's license.

Armed protesters started occupying the Malheur Wildlife Refuge on Jan. 2, following a peaceful protest in support of ranchers Dwight and Steven Hammond. The occupation came to an end on Feb. 11.
