CAIRO (TheStreet) -- The top leadership body of Egypt's ruling party stepped down Saturday, although President Hosni Mubarak remained in office, the Associated Press reported.

Protesters said the resignations weren't sufficient and said they would continue to press for Mubarak to step down, the

AP

said. The news service added that tens of thousands of people converged on Cairo's Tahrir Square for a 12th day, chanting, "He will go! He will go!"

The U.S., however, endorsed the handling of the transition by Egypt's Vice President Omar Suleiman, the

AP

reported.

"It's important to support the transition process announced by the Egyptian government actually headed by now-Vice President Omar Suleiman," Secretary of State Hillary Rodham Clinton said at an international security conference in Munich, Germany, according to the

AP

And Frank Wisner, the retired U.S. diplomat sent by President Obama to Cairo in recent days, said Mubarak had to retain a leadership position at least temporarily if the "fragile glimmerings" of progress were to take hold as quickly as needed, the

AP

also reported.

Mubarak wants to stay in his post until after presidential elections are held in September.
