Adam Savader, 21, of Great Neck, N.Y. faces charges of cyberstalking and blackmail, Politico reported Wednesday.
Savader is accused of illegally obtaining nude photos of 15 young women and threatening to make them public unless they provided more photos.
A political science student at State University of New York Farmingdale, Savader has interned for GOP presidential candidate Mitt Romney, GOP vice presidential candidate Paul Ryan and former House Speaker Newt Gingrich.
Prosecutors said he preyed on women from Michigan, Washington, D.C., and Long Island.
In one instance he threatened to send naked pictures of one of his victims to the Republican National Committee if she didn't comply with his demands, the criminal complaint said.
A bail hearing for Savader is scheduled Friday. He will be prosecuted in Michigan where the case was first reported, authorities said.
