  We show that recent results in the paper of Jaffe et al on evidence of
vorticity and shear of the Universe are incorrect. They fit WMAP data with
certain Bianchi model which is known to have a vanishing vorticity. The
performed fit of the shear is not reliable because the respective formula seems
not to be gauge invariant. We suggest a theoretical framework to analyze
asymmetric large scale WMAP data.
