Lamb files candidacy paperwork for Oklahoma governor's race

Lamb filed a statement of organization with the Oklahoma Ethics Commission and issued a statement in which he said he was "strongly considering" running in 2018.

"Since being elected lieutenant governor in 2010 I have visited each of Oklahoma's 77 counties on an annual basis, listening and talking to Oklahomans regarding issues of importance to them and our great state," Lamb said.

Earlier this year, Lamb resigned his post on Fallin's cabinet as a small-business advocate, citing a disagreement with the governor over her plan to broaden the sales tax to a variety of services as a way to help shore up the state's budget shortfall.
