Donald J. Trump perhaps thought he was being magnanimous in declaring he wouldn’t seek a special prosecutor to examine whether Hillary Rodham Clinton broke any laws while she served as secretary of state.

Except for one thing … or so I understand.

The president-elect has no actual authority to make such a ruling.

That process starts and stops with the Justice Department and the FBI. Moreover, I am pretty sure the feds have determined already that Clinton didn’t commit any crimes while she used a personal e-mail server.

The FBI actually has made that declaration twice.

FBI Director James Comey said in July that “no reasonable prosecutor” would bring charges against Clinton. Eleven days before the election, Comey then said he was examining some newly discovered e-mails to see if they contained any new information. Nine days after that, Comey said his initial conclusion stood.

Of course, that didn’t stop the future president-elect from convicting Clinton of crimes she didn’t commit. He vowed to pick a special prosecutor.

Now he says he won’t.

That’s not his call to make.
