The all-too-brief search for national unity has ended.

Donald J. Trump said his State of the Union speech would be a unifying message. The president delivered it Tuesday night and then went on another Twitter tirade that blamed Democrats for the failure to reach an agreement on immigration reform.

Then the president officially called off the unity quest this morning. He agreed with the release of a memo written by Republican House Intelligence Committee Chairman Devin Nunes that accuses the FBI of bias in its investigation of the Russian meddling allegation.

The memo release has launched yet another partisan battle. Democrats opposed its release; Republicans favored it. The FBI opposed it, too. Its release just might trigger the resignation of FBI director Christopher Wray, whom Trump selected to lead the agency. Who knows, too, whether the release is the last straw for the attorney general, Jeff Sessions, who has drawn plenty of presidential pique himself because he decided to recuse himself from the Russia probe.

I am no Sessions fan, but he made what I consider to be the right decision by recognizing his own bias in the Russia investigation, given his former role as a key member of Trump’s presidential transition team.

So, the president has now pitted the parties against each other; he also has squared off against the Department of Justice and the FBI. It’s now Trump vs. the DOJ/FBI.

Unity? Are you kidding me?

The president isn’t wired to unify anyone. He thrives on confrontation. He basks in conflict. He glories in calling attention to himself.

Oh, and have I mentioned that Donald Trump is unfit to lead the greatest nation on Earth? Hey! I just did!
