We present results from an ongoing program of Chandra X-ray imaging and spectroscopy of lensing clusters of galaxies. The X-ray data provide clear evidence that the program objects, including Abell 370, EMSS1358+6245 and EMSS1054-0321, exhibit a variety of dynamical states. Spatial variations in plasma temperature are observed, at differing levels of significance, in all of these clusters. For the first two clusters, which are strong lenses, we compare the quantity and spatial distribution of mass inferred from the lensing data with that obtained from the X-ray emitting gas. We also discuss the X-ray source density/flux relationship (logN-logS) observed in these 50-90 ks Chandra exposures.
