THE TIGHTENING NOOSE:

In a string of 10 Twitter messages -- which began after 11 p.m. Saturday and ended around noon Sunday, and which included profanity and misspellings -- Trump opened a window into his state of mind, even as Trump's representatives at a global security conference in Germany advised jittery allies to generally ignore the president's tweets.

Trump's latest attacks built on remarks last week in which he misrepresented the evidence revealed by Mueller. He tweeted falsely, "I never said Russia did not meddle in the election." He blamed President Barack Obama's administration for doing "nothing" to stop the intrusion. Trump rebuked national security adviser H.R. McMaster for publicly saying the evidence of Russian interference was "incontrovertible."

And he held the FBI responsible for last week's devastating shooting at a Parkland, Fla., high school that left 17 dead. Trump tweeted that the bureau was committing so many resources to the Russia probe that it missed "all of the many signals" about the shooter.

One topic Trump avoided in his missives was punishment of Russia. [...]

Trump sent the messages from his Mar-a-Lago estate in Palm Beach, Fla., where he was ensconced for two days. He spent much of the time watching cable news, venting to friends about the Russia investigation and complaining that it has been driving so much press coverage, according to people who have spoken to him. The president also surveyed Mar-a-Lago Club members about whether he ought to champion gun control measures in the wake of last week's school massacre in nearby Parkland, telling them that he was closely monitoring the media appearances by some of the surviving students, according to people who spoke with him there.
