I must presume that Rudy Giuliani is a good lawyer. He once was a federal prosecutor in New York before becoming mayor of the nation’s largest city.

He’s run for president a couple of times. He’s now back in private practice, representing clients, one of whom is the president of the United States, Donald J. Trump.

Now the ex-mayor says this, that Trump can ignore a subpoena issued by special counsel Robert Mueller if it comes. Yes, the president can ignore a federal subpoena, says Giuliani.

Hold on! I thought that “no one is above the law.” Presidents of the United States are citizens of the same country as you and I — and Rudy Giuliani. Aren’t they subject to the same demands that fall on the rest of us?

Giuliani has entered the fray involving Trump and Stormy Daniels, the porn queen who alleges having a fling with Trump back in 2006. Trump denies it. Yet his personal lawyer, Michael Cohen, paid Daniels $130,000 to buy her silence about the alleged tumble — that Trump said didn’t occur.

Mueller is likely looking into it to determine if there’s possibly a campaign finance law violation.

He might summon Trump to answer questions from the grand jury.

Giuliani says the president doesn’t have to testify.

So, is the president above the law?
