Donald Trump’s lawyer, John Dowd, says the president “cannot obstruct justice” because the law exempts him from doing so.

Dowd said: The “president cannot obstruct justice because he is the chief law enforcement officer … and has every right to express his view of any case.”

Are you clear on that? Me, neither.

Oh, but now we have this tidbit regarding the attorney general of the United States, Jeff Sessions. Nearly two decades ago, when President Bill Clinton was being tried in the U.S. Senate after the House impeached him, Sessions — then a Republican senator from Alabama — said this while making the case to remove the president from office:

“The facts are disturbing and compelling on the president’s intent to obstruct justice.”

There’s more.

“The chief law officer of the land, whose oath of office calls on him to preserve, protect and defend the Constitution, crossed the line and failed to defend the law, and, in fact, attacked the law and the rights of a fellow citizen.”

Dadgum, man! Who’s right? The president’s personal lawyer or the attorney general?

Dowd is reaching way beyond his — and the president’s — grasp, in my view, in contending that Trump is immune from the obstruction of justice complaint, were it to come from the special counsel probing the Russian interference in our 2016 presidential election.

I disagree with what Sessions said in 1999 about President Clinton, but his statements on the record during that trial put him squarely at odds with what Trump’s personal lawyer is trying to peddle today. If an earlier president can be charged with obstruction of justice, then surely so can the current president face such a charge if one comes forward from the special counsel’s office.

This all begs the question from yours truly: What kind of legal mumbo jumbo is Trump’s lawyer trying to peddle?
