The officials, who were not immediately identified, were sent home from Kentucky Speedway on Friday evening, a person familiar with the NASCAR investigation told the AP. The person requested anonymity because NASCAR's investigation is ongoing.
Mauricia Grant filed her suit Tuesday, alleging 23 specific incidents of sexual harassment and 34 specific incidents of racial and gender discrimination during her time as a technical inspector for NASCAR's second-tier Nationwide Series.
Grant, who is black, claims her October 2007 firing was retaliation for complaining about the way she was treated on the job from her January 2005 hiring.
NASCAR sent a team of investigators from its human resources and legal offices to Kentucky this weekend to interview those named in the suit. Of 27 interviews conducted away from the track Thursday and Friday, two officials were found to have engaged in behavior that violated NASCAR policy.
Their leave is indefinite, but paid.
"We take this issue very seriously, and we're going to always do everything we can to maintain a professional work place," NASCAR spokesman Ramsey Poston said.
NASCAR chairman Brian France has not addressed the validity of Grant's claims, but said the former official never made a formal complaint or followed NASCAR policy in reporting harassment.
Investigators have failed to uncover a single instance where Grant complained to her supervisors or other NASCAR employees about the way she was treated, and NASCAR plans to continue defending the organization against the lawsuit, the person familiar with the investigation told AP.
Grant has said she followed the chain of command all the way to Nationwide Series director Joe Balash, but stopped short of telling human resources because she was reprimanded by that department for a separate incident two weeks after lodging her complaint. She said she viewed the reprimand, which included a threat of termination, as retaliation for complaining to Balash.
Named in the suit are Balash, assistant series director Mike Dolan, two supervisors, NASCAR's senior manager for business relations, the human resources director and 17 officials who were Grant's co-workers.
The two employees placed on leave Friday were among those 17 officials. Balash, Dolan and the two supervisors remained on site in Kentucky for Saturday night's Nationwide Series race.
Grant's lawyer, Benedict P. Morelli of Morelli Ratner PC, called NASCAR's action "unbelievable and astonishing" but said it was too little too late for his client.
