Election officials in Egypt now say the results of last weekend's presidential runoff will be released tomorrow.

The announcement, originally due Thursday, was postponed after both candidates claimed victory and accused each other of voting irregularities. The delay has led to speculation that Egypt's military rulers are holding results hostage to bargaining and backroom deals.

The election pitted Muslim Brotherhood candidate Mohammed Morsi against the last prime minister during Hosni Mubarak's rule, Ahmed Shafiq.

Meanwhile, Egypt's liberal political parties are accusing the U.S. of trying to sway the results of the elections. In a strongly worded statement today, a bloc of liberal parties in parliament says the United States is pressuring the ruling military council to hand power to the Brotherhood.

On Wednesday, U.S. Secretary of State Hillary Rodham Clinton demanded that the military "support the democratic transition, to recede by turning over authority."

The liberal parties also accuse the Muslim Brotherhood of "hijacking" the revolution.
