(Newser) – Hillary Clinton's campaign manager quit today, reports ABC News, giving no explanation in an email to staffers other than the campaign "has required enormous sacrifices from all of us and our families." Patti Solis Doyle will stay on as a senior adviser, but passes the torch to Maggie Williams, who led Clinton's staff when she was first lady.

Clinton praised Solis Doyle for getting her "within reach of the nomination," MSNBC reports, echoing her thoughts that the campaign has required great sacrifice. Solis Doyle started working for Hillary during Bill Clinton's 1992 run for the White House, and became the first Latina to lead a presidential campaign. Her resignation comes the day after Barack Obama swept Clinton in four primary and caucus races.
