“I wonder how many [White House] staff told Wolff things off the record that he then used on the record,” Bloomberg View columnist Joe Nocera tweeted Thursday. “He’s never much cared about burning sources. Can’t imagine that many of those quotes were meant for publication.”

Steven Rattner, a journalist-turned-financier and former Obama auto czar, tweeted Thursday that “[Steve] Bannon may well have said all that stuff but let's remember that Wolff is an unprincipled writer of fiction.”

Wolff and Rattner have a history of animosity, with Wolff writing critically about Rattner in his 2003 book, “Autumn of the Moguls,” and also in Vanity Fair. And then there’s Rattner’s claim that Wolff used his 7-year-old son, on a play date with one of Rattner’s children, to extract information. He’s “a total sleazebag,” Rattner tweeted.

Wolff ... has faced accusations in the past of playing loose with facts in his columns and books, and of not honoring ground rules with sources.

In a 2004 profile, The New Republic’s Michelle Cottle wrote that “the scenes in his columns aren't recreated so much as created — springing from Wolff's imagination rather than from actual knowledge of events.” Instead of conventional reporting, she wrote, Wolff “absorbs the atmosphere and gossip swirling around him at cocktail parties, on the street, and especially during those long lunches at Michael's."
