We report on a recent re-examination of dark matter constraints from halo wide stellar binaries, motivated by observations we made of four of the very wide binary candidates on which earlier constraints were based. Our new data suggest that the current stellar binary data place only weak constraints on the properties of dark matter in the halo of the Milky Way.
