The Inquiry about the ties between Russia and President Trump’s campaign to include woman who ran upscale escort service

A woman who once ran an upscale New York City escort service will appear on Friday before a federal grand jury that is hearing evidence in the wide-ranging inquiry into ties between Russia and President Trump’s 2016 election campaign, according to a person familiar with the matter.

The New York Times said that the woman, Kristin M. Davis, was interviewed last week by officials from the office of the special counsel, Robert S. Mueller III, who is looking into the Trump campaign’s links to Russian operatives.

Known in New York tabloids as the “Manhattan Madam,” Ms. Davis is perhaps best remembered for having claimed in 2008 that she provided escorts to Eliot Spitzer, who resigned that same year as governor of New York after The New York Times reported that he had become ensnared by a federal investigation into a different prostitution ring. Mr. Spitzer has denied any ties to Ms. Davis, 43, who spent four months on Rikers Island for running her escort service.
