The cable network's coverage of Trump transition team member Anthony Scaramucci came amid federal scrutiny of corporate parent Time Warner's pending purchase by AT&T — and the widespread belief among media execs that CNN President Jeff Zucker can't survive a merger.

CNN immediately caved after Scaramucci, a financier and frequent network guest, cried foul and threatened to take legal action, sources said Tuesday.

Scaramucci got an unusual public apology but still hired a top Manhattan lawyer to put further pressure on CNN and "look after [his] interests in this matter," one source said.

Sources also said the three journalists responsible for the retracted story — reporter Tom Frank, editor Eric Lichtblau and Lex Haris, who headed the CNN Investigates unit — were urged to resign.
