Washington (CNN) The one-sided feud between President Donald Trump and his attorney general persisted Wednesday, even as a battered Jeff Sessions trudged ahead with his Justice Department duties.

Less than an hour after Sessions was deposited at the White House by a black SUV for routine meetings in the West Wing, Trump proclaimed from another corner of the same building that his displeasure in his attorney general hasn't waned.

"Why didn't A.G. Sessions replace Acting FBI Director Andrew McCabe, a Comey friend who was in charge of Clinton investigation but got big dollars ($700,000) for his wife's political run from Hillary Clinton and her representatives," he tweeted. "Drain the Swamp!"

The message, which stretched facts, was the latest chapter in a humiliating ordeal for the nation's top law enforcement official, who has refused to resign even amid the increasingly hostile barbs being issued by his boss. Over the past two days, Trump has deemed his attorney general "beleaguered" and "very weak." His anger has stemmed from Sessions' decision to recuse himself from an FBI investigation into Russian election meddling.

Even as Sessions was attending a so-called "principals small group meeting" in the West Wing on Wednesday, Trump -- who remained in his private residence -- declined to confront his attorney general face-to-face. Some of Trump's aides have encouraged the President to speak with Sessions directly, rather than angrily lambast him over Twitter, but that advice appeared to go unheeded Wednesday morning.
