  We show that the failure of the Delaney-Greer (DG) variational ansatz for
transport demonstrated by us in Phys.\ Rev.\ B {\bf 80}, 165301 (2009) (I) is
not related to an unsuitable constraint that prevents a broken time-reversal
symmetry or to real orbitals, as DG incorrectly claim. The complex orbitals
suggested by them as a way-out solution merely represent a particular case of
the general case considered by us in I, which do not in the least affect our
conclusion.
