We report results of a study of the ionized gas towards the Galactic center with radio recombination lines at cm wavelengths. Both the Green Bank Telescope and the Very Large Array were utilized to probe the kinematics of the ionized gas on a global scale for both diffuse and discrete sources within the inner 2.0° × 0.5° (l × b). A diffuse ∼0 km s−1 gas, a thermal flux continuum fraction exceeding 40%, and an asymmetry where ∼70% of the ionized gas is found at positive Galactic longitudes are the preliminary results briefly discussed here.
