President Donald Trump has fired the chair of the Tennessee Valley Authority, claiming it has betrayed American workers.

Trump also claimed the outgoing chairman was paid too much.

Trump made the announcement as he signed an executive order to require all federal agencies to complete an internal audit to prove they are not replacing qualified American workers with people from other countries.

The president told reporters at the White House today he was formally removing the authority’s chair of the board and another member of the board and threatened to remove other board members if they keep hiring foreign labor.

Trump said the TVA board must immediately hire a new chief executive officer that “puts the interests of Americans first.”

The TVA is a federally owned corporation created in 1933 to provide flood control, electricity generation, and economic development to the Tennessee valley. The region covers most of Tennessee and parts of Alabama, Mississippi, Kentucky, Georgia, North Carolina and Virginia.
