We discuss the preliminary results from radio polarization observations of 22 compact steep spectrum sources made with the VLA at 1.3 cm wavelength. We confirm that 1) the detection of a flat-spectrum synchrotron halo and a radio bridge in two CSSs, suggesting that they may be young sources, 2) CSS galaxies with two lobes of emission asymmetric to the core position show strong polarization asymmetry with the highest polarized emission arising from the component farther away from the core and 3) Source components which are nearest to the cores are generally unpolarized even at such short wavelength, suggesting that the spread in the λ2 polarization spectra is much narrower than in extended sources.
