Police are investigating the complaint made by the waitress.
The U.S. Attorney's Office is expected to review the evidence in the case to see what, if any, charges may be brought against Haynesworth.
"There seems to be no truth to these allegations. We are currently evaluating facts and considering our own legal action against those involved."
According to a police report obtained by NBC Washington, the waitress stated that her hands were full carrying glasses as she was clearing the table at about 1:30 a.m. Sunday.
She said that "Subject 1" tried to pay his bill by giving her his credit card, but he asked if it was OK to stick the card in her blouse near her breast area. She nodded her head yes and, according to the report, she said he then placed the card into her blouse gently, sliding the card further into her left side of the blouse and then started to caress her breast.
Haynesworth’s name is not mentioned in the report, which was filed at 5:15 a.m. Sunday, but sources say that "Subject 1" is indeed referring to Haynesworth.
On Saturday morning, Haynesworth and his lawyer went to the Reston police station, where he was charged with assault stemming from an incident on February 2 in which a man said the football player hit him while he was sitting in his car.
Haynesworth, 29, signed a summons releasable warrant, charging him with assault, and then departed the police station. He is due in Fairfax County Criminal Court at 9:30 a.m. on March 31.
