Perils mount for the Trump presidency.

The shift of power in Congress and news reports are combining to confront President Trump with the prospect of a protracted and intense political war for survival “that may make the still-unresolved partial government shutdown pale by comparison,” writes our chief White House correspondent.

News reports: A Times report detailed how, after Mr. Trump fired James Comey as F.B.I. director, the bureau became so concerned by the president’s behavior that they took the aggressive step of opening a counterintelligence inquiry into whether he had been working on behalf of Russia.

And The Washington Post reported that the president had taken extensive steps to conceal his conversations with Russia’s President Vladimir Putin over the past two years.
