WASHINGTON — For weeks, Washington has waited to hear what he had to say. So when John R. Bolton, the president’s former national security adviser, popped back up on Twitter on Friday morning with a teasing message, it sent the town, well, all atwitter.

“Glad to be back on Twitter after more than two months,” Mr. Bolton wrote. “For the backstory, stay tuned……..”

Was he finally going to describe his internal opposition to President Trump’s efforts to pressure Ukraine for damaging information about his Democratic rivals? Would he confirm that he called the whole thing a metaphorical “drug deal” and considered Rudolph W. Giuliani a “hand grenade who’s going to blow everybody up”?

Sorry, no go. Over the course of the day, Mr. Bolton posted a few more messages — not about the Ukraine matter that has propelled his former boss to the edge of impeachment but about his own two-month battle to “liberate” his Twitter account, as he put it, from a White House that refused to give it back when he resigned in September in a flurry of acrimony.
