Following the Weinberg formulation of the group-theoretical approach to quantum field theory, we construct an expression that can serve as the massive generalization of the Weinberg potential for a free photon. This massive expression transforms like a vector under three-dimensional rotations. If we let the mass go to zero, then this massive expression transforms under a homogeneous Lorentz transformation exactly like the photon potential, i.e., like a four-vector up to a gradient term. In addition, the helicity-zero component of the massive expression remains suppressed in the zero-mass limit for all Lorentz observers.
