Nevada rancher Cliven Bundy said Monday that the occupation at the Malheur National Wildlife Refuge would continue.

In a notarized letter from Clark County, Nevada, Bundy wrote to Harney County Sheriff David Ward that “We the People of Harney County and also We the People of the citizens of the United States DO GIVE NOTICE THAT WE WILL RETAIN POSSESSION OF THE HARNEY COUNTY RESOURCE CENTER.

The letter was also sent by certified mail to Oregon Gov. Kate Brown and President Barack Obama.
