CLEVELAND -- The federal government wants Ohio to take down a giant Cavs sign featuring LeBron James, but Ohio's governor is throwing his support behind the sign.

Crews posted a huge Nike "We Are All Witnesses" sign on the eastern face of the Sherwin Williams building, but federal officials spotted the sign at a recent convention.

They said it violates a highway beautification act passed during the Johnson Administration.

Ohio Gov. Ted Strickland said there are exceptions and on Wednesday he defended the sign in person.

"We are determined to do everything to make sure that this city has the opportunity to continue to enjoy this beautiful display of commercial art," said Strickland.

The sign is staying up, at least for now.
