delivered a speech on the water crisis in San Joaquin Valley that Nunes described as "little more than lip service and a rehash of what he has said on the subject for years."

Nunes made the resignation call without consulting with any other congressional lawmakers or his own leadership, said House.

"We see this as an urgent issue that needs to be resolved," House said. "The pumps need to be turned on"
