A prominent political donor purchased a Rolex watch for Virginia Gov. Robert F. McDonnell, according to two people with knowledge of the gift, and the governor did not disclose it in his annual financial filings. The $6,500 luxury watch was provided by wealthy businessman Jonnie R. Williams Sr., the people said. He is the chief executive of dietary supplement manufacturer Star Scientific and the person who paid for catering at the wedding of the governor’s daughter. The people spoke on the condition of anonymity because of an ongoing federal investigation into the relationship between Williams and the McDonnell family. and later on in the same article They are also investigating other money provided to Maureen McDonnell, as well as expensive designer clothing — some bought in 2011 in New York City — according to people familiar with the inquiry. The shopping trip emanated from a social occasion with Williams and Maureen McDonnell shortly after the governor won election. The governor’s wife mentioned that she would need an inauguration dress, preferably one from the designer Oscar de la Renta, and would like Williams’s help getting one, according to two people familiar with her suggestion. Williams agreed to buy one for her, but a top staffer to the governor advised Williams and the first lady that such a gift was not allowed. A year later, the first lady contacted Williams to propose that he take her shopping at Bergdorf Goodman, the people familiar with the shopping said. In that store, Williams purchased an estimated $15,000 in clothing for Maureen McDonnell, they said.
