State police said Friday they are looking into allegations, raised in a television news report, of drug-related wrongdoing by U.S. Sen. Charles S. Robb in the 1980s while he was governor of Virginia.

After Gov. L. Douglas Wilder's office denied an investigation was under way, state police called their probe an "inquiry."Robb, a Democrat, has been plagued by allegations he attended parties where drugs were used openly. In a book released Thursday, Virginia Beach private investigator Billy Franklin wrote that Robb repeatedly used cocaine when he was governor from 1982 to 1986.

The senator has denied any wrongdoing and said Friday he welcomed any investigation because it would quash false accusations.

"We are conducting an inquiry," state police spokesman Charlie Vaughn told The Associated Press. "An inquiry is simply a contact by us with the people making the allegations to confirm the allegations and to ask them about the allegations."

Asked if state police would look into allegations that Robb used cocaine while governor, Vaughan had told The Roanoke Times & World-News: "That's all-inclusive. . . . Anything that indicates a criminal allegation."

Tai Collins, 28, a former Miss Virginia-USA from Roanoke, claims she had an affair with Robb, 51, while he was governor in 1984.

Vaughan said the probe began as a result of numerous allegations made by Collins and others, including statements broadcast April 28 on the NBC News program "Expose."

On the show, Collins did not accuse Robb of using cocaine.

Robb has denied having a sexual affair with Collins. Asked again Friday if he had ever used drugs or been in the presence of people using drugs, Robb said, "Never. Absolutely. Categorically."
