  The reported CP asymmetry in D->K^+K^- / pi^+pi^- is argued to be too large
to naturally fit the SM. If so, a new source of CP violation is implied in the
Delta C=1 sector with a milliweak strength. CP-odd interactions in the
flavor-diagonal sector are strongly constrained by the EDMs placing severe
limitations on the underlying theory. While the largest effects usually come
from the New Physics energy scale, they are strongly model-dependent. Yet the
interference of the CP-odd forces manifested in D decays with the conventional
CP-even Delta C=1 weak interaction generates at the charm scale a background
level. It has been argued that the d_n in the SM is largely generated via such
an interference, with mild KM-specific additional suppression. The reported CP
asymmetry is expected to generate d_n of 30 to 100 times larger than in the SM,
or even higher in certain model yet not quite natural examples. In the SM the
charm-induced loop-less |d_n| is expected around 10^{-31}e*cm. On the technical
side, we present a compact Ward-identity--based derivation of the induced
scalar pion-nucleon coupling in the presence of the CP-odd interactions, which
appears once the latter include the right-handed light quarks.
