The internal rotation of the Sun is determined from each of the six available sets of solar oscillation splitting data. These data span this activity cycle and best sample the region near the base of the convection zone. Going inwards through the convection zone into the outer radiative interior, the robust results are a decrease in the rotation rate in the equatorial plane and a trend away from the surface-like differential rotation toward solid body rotation. In the equatorial plane of the radiative interior, the rotation rate seems to systematically increase through the solar cycle. If true, this suggests that the interior has a role in the activity cycle.
