Only in New York would a district attorney open a probe into #MeToo allegations against the man investigating his own office for mishandling a #MeToo claim against one of his wealthy donors.

Gov. Andrew Cuomo has already pushed back, saying Tuesday, “It’s very important the DAs who do the investigations do not have the whiff or perception of conflict.”

He plainly means Manhattan DA Cy Vance, who’s already announced he’s on the Eric Schneiderman case.

Yet Schneiderman’s now-former office is, as Cuomo ordered in March, looking into Vance’s handling of a sex-assault case involving Harvey Weinstein three years ago. That’s far more than a whiff of conflict.

Vance can’t control Schneiderman’s case, and neither can his top people. If Cuomo has to name a special prosecutor, so be it.
