  The propagator for the massless vector field in de Sitter space cannot
maintain de Sitter invariance in the general covaraint gauge, except in the
exactly transverse gauge limit. This is due to a previously overlooked
Ward-Takahashi identity that the propagator must satisfy. Here we construct the
propagator that satisfies all the conditions of a consistently quantized
theory. Our solution preserves cosmological symmetries and dilations, but
breaks spatial special conformal transformations. The solution amounts to
adding a homogeneous de Sitter breaking term to previously reported de Sitter
invariant solutions of the propagator equation of motion. Even though the
corrections we report pertain to the gauge sector of the linear theory, they
are relevant and have to be accounted for when interactions are included.
