A federal elections commissioner has called Donald J. Trump’s bluff.

Good for her!

The challenge has come from Ellen Weintraub, a commissioner from New Hampshire, who is demanding that the president of the United States provide proof of allegations he has made about “widespread voter fraud” in the 2016 presidential election.

Trump has said “millions” of illegal immigrants voted for Hillary Rodham Clinton, resulting in her hefty popular vote margin over the actual “winner” of the presidential election.

In so doing, Trump has impugned the integrity of the U.S. electoral process, not to mention that of state and local elections officials throughout the nation.

He hasn’t produced a shred, a scintilla, a scant hint of evidence to back up what he has alleged.

It’s time for Trump to produce the goods. Weintraub said Trump has in effect accused elections officials of committing “thousands” of felony crimes.

According to The Hill: “The President has issued an extraordinarily serious and specific charge,” added Weintraub, who was appointed by former President George W. Bush. “Allegations of this magnitude cannot be ignored. I therefore call upon President Trump to immediately share his evidence with the public and with the appropriate law-enforcement authorities so that his allegations may be investigated promptly and thoroughly.”

Well, Mr. President? Play your hand, sir.
