Research Abstract	To solve the local cohomology problem for the exact cancellation of gauge anomaly in chiral lattice gauge theories, we proposed a method to use the local and gauge-covariant Chern-Simons current in Field-Tensor expansion. We showed that this method works for the two-dimensional SU(N) chiral lattice gauge theories, and checked it numerically.
