New York (CNN Business) Former New York Times Executive Editor Jill Abramson said Wednesday night that she was reviewing passages in her new book after being accused of plagiarism.

"I take seriously the issues raised and will review the passages in question," she said on Twitter

Abramson, whose book "Merchants of Truth" was released Tuesday, had previously been defiant in the face of the plagiarism allegations, telling Fox News host Martha MacCallum just hours earlier, "I certainly didn't plagiarize in my book."

The allegations against Abramson were made Wednesday by Michael Moynihan, a "Vice News Tonight" correspondent, who accused her on Twitter of plagiarizing multiple passages in the book.

Moynihan offered several examples in which the language used by Abramson was similar to language that first appeared elsewhere.

The following examples from the final book—not the galley—are only from the Vice chapters (I didn't check the others).
