"It's bizarre," said one insider, who was left wondering who's in charge ahead of today's coverage of the history-making inauguration of Barack Obama as president.
Added another insider, "If any of the top editors know what's going on, they're not telling anyone."
Meanwhile, Debby Krenek, another managing editor, was seen in the paper's Melville, LI, offices after being absent Thursday and Friday.
Her presence yesterday fueled speculation that Krenek, who's primarily in charge of Newsday's online edition, might be tapped by owner Cablevision to replace Mancini.
"She's here, but she's in a meeting," said a person answering Krenek's office phone.
There has been no confirmation or comment of any kind from Newsday and Cablevision officials.
