Chicago Mayor Rahm Emanuel cut short his two-week vacation in Cuba to rush home Tuesday amid growing calls for his resignation over the city’s police shooting scandal.

Yet even as his critics loudly demand he step down, there has been virtual silence from Emanuel’s oldest friends and political allies: Hillary Clinton and Barack Obama.

It’d be hard to defend the apparent coverup of the October 2014 fatal shooting of Laquan McDonald, 17 — a coverup that protected Emanuel in the runup to his narrow re-election that year.

For 400 days, Chicago authorities failed to disclose the existence of a dashboard video that discredited police accounts of the shooting. A week after winning re-election, Emanuel announced a $5 million settlement with the family obligating both sides to keep quiet about the video.

Only when a journalist successfully sued was the video made public — just hours after the cop was indicted for murder.

Polls now show a majority of Chicagoans want Emanuel to quit, and 64 percent say he lied in denying having seen the video.

Obama has had little to say — though Emanuel is his former chief of staff and Chicago’s his hometown and the future site of his presidential library. Huh: The president wasn’t as restrained about police controversies from Ferguson to Baltimore.

Clinton’s been equally mum, though Emanuel was her husband’s senior adviser — and despite her own outspoken remarks about police shootings elsewhere.

She says only that she’s “confident that [Emanuel is] going to do everything he can to get to the bottom of these issues.”

Bernie Sanders, with less baggage here, is far more on-point, saying: “Any elected official with knowledge that the tape was being suppressed or improperly withheld should resign.”

As Chicago’s scandal continues to fester, it’s hard to see how Clinton can possibly “replenish our depleted reservoirs of trust,” as she promises, until she breaks her silence and addresses Emanuel’s coverup head-on.
