Republican candidate Mitt Romney was listed as the chairman and CEO of Bain Capital on government documents years after he says he gave up control of the private equity firm, The Boston Globe revealed Thursday in a report that intensified a war of words between the rival campaigns.

Romney has said he left the firm in February 1999 to take charge of the 2002 Winter Olympics in Salt Lake City and has repeatedly used that as a defense when asked about bankruptcies and worker layoffs at Bain-controlled companies after that date.

The Globe, however, said it found nine SEC filings that describe Romney as running the company after that point. The report said some indicate he had control of five Bain Capital entities formed in January 2002.

In addition, the newspaper said Massachusetts disclosure forms indicate that Romney made at least $100,000 as a Bain “executive” in 2001 and 2002, apart from his investment earnings. They also show he was paid as a Bain executive while he was directing the Olympics, the Globe reported.

“The article is not accurate,” said Romney spokesperson Andrea Saul in a statement responding to the story. “As Bain Capital has said, as Governor Romney has said, and as has been confirmed by independent fact checkers multiple times, Governor Romney left Bain Capital in February of 1999 to run the Olympics and had no input on investments or management of companies after that point.”

The newspaper said a Romney campaign source blamed discrepancies in the SEC forms on legal quirks and technicalities.

Later Thursday, Bain Capital said in its own statement that Romney “has had absolutely no involvement with the management or investment activities of the firm or with any of its portfolio companies” since he left the company in February 1999.

“Due to the sudden nature of Mr. Romney’s departure, he remained the sole stockholder for a time while formal ownership was being documented and transferred to the group of partners who took over management of the firm in 1999,” Bain said. “Accordingly, Mr. Romney was reported in various capacities on SEC filings during this period.”

The Boston Globe report, however, added to questions about Romney’s personal finances that have plagued his campaign in recent days. Romney’s Democratic opponents have hit at him for releasing just one year of tax returns and for not disclosing more information about his funds held in known tax havens outside the U.S.

President Obama’s campaign immediately seized upon the Globe report, with spokesman Ben LaBolt asking in a tweet: “Did Romney lie to the American people or the SEC?”

This latest debate over Romney’s tenure at Bain prompted some of the harshest language of the general election race to date.

Earlier Thursday, the Romney campaign had released an ad accusing Obama of running a “dishonest campaign” and distorting the facts about Romney’s tenure at Bain.

“When a President doesn’t tell the truth, how can we trust him to lead?” the ad’s narrator asks.

The rhetoric escalated in an Obama campaign conference call with reporters, during which deputy campaign manager Stephanie Cutter said Romney may have committed a felony if he lied to the SEC about the timing of his departure from Bain.

Cutter said Romney should release tax returns to back up his claim he left the firm in 1999. “If the SEC filings aren’t accurate, then prove it,” she said.

Senate Majority Leader Harry Reid, D-Nev., also chimed in to say that the confusion over Romney’s records disqualified him from even a lowly government post, Politico reported.

“He not only couldn’t be confirmed as cabinet secretary, he couldn’t be confirmed as a dog catcher, because a dog catcher – you’re at least going to want to look at his income tax returns,” Reid said.
