Applying squashing transformation to Kerr-Godel black hole solutions, wepresent a new type of a rotating Kaluza-Klein black hole solution to thefive-dimensional Einstein-Maxwell theory with a Chern-Simon term. The newsolutions generated via the squashing transformation have no closed timelikecurve everywhere outside the black hole horizons. At the infinity, the metricasymptotically approaches a twisted S^1 bundle over a four-dimensionalMinkowski space-time. One of the remarkable features is that the solution hastwo independent rotation parameters along an extra dimension associated withthe black hole's rotation and the Godel's rotation. The space-time also admitsthe existence of two disconnected ergoregions, an inner ergoregion and an outerergoregion. These two ergoregions can rotate in the opposite direction as wellas in the same direction.
