In private, President Trump spent much of the past week brooding, like he often does. He has been anxious about the Russia investigation’s widening fallout, with his former campaign chairman now standing trial. And he has fretted that he is failing to accrue enough political credit for what he claims as triumphs.

At rare moments of introspection for the famously self-centered president, Trump has also expressed to confidants lingering unease about how some in his orbit — including his eldest son, Donald Trump Jr. — are ensnared in the Russia probe, in his assessment simply because of their connection to him.

Yet in public, Trump is a man roaring. The president, more than ever, is channeling his internal frustration and fear into a ravenous maw of grievance and invective. He is churning out false statements with greater frequency and attacking his perceived enemies with intensifying fury. A fresh broadside came on Twitter at 11:37 p.m. Friday, mocking basketball superstar LeBron James and calling CNN’s Don Lemon “the dumbest man on television.”

This is the new, uneasy reality for Trump at an especially precarious moment of his presidency, with the Republican Party struggling to keep control of Congress, where a Democratic takeover brings with it the specter of impeachment, and special counsel Robert S. Mueller III’s grip seeming to tighten on the president and his circle.
