The production of W and Z bosons is studied in pp collisions at center-of-mass energies of both 7 and 8 TeV using data collected by the CMS experiment. W events are characterized by an isolated, energetic electron or muon. Z events are characterized by a pair of isolated, energetic electrons or muons. Data-driven methods are used to estimate reconstruction and triggering efficiencies, as well as the yields of the main backgrounds. Recent results on Z boson differential cross section, Z boson angular coefficients, photon final-state radiation in Z decays, forward-backward asymmetry in Drell-Yan process, and W muon charge asymmetry are presented.
