A vibrant B physics program is being pursued at the Tevatron for Run II using the upgraded accelerator complex and the upgraded CDF and D0 detectors with the goal of collecting 2 fb1 of integrated luminosity. This will provide measurements of various CP parameters which both complement and extend the programs at the B factories. These are also a variety of spectroscopy measurements currently available only at the Tevatron. The detectors are now largely commissioned and data acquisition is underway.
