WASHINGTON—A little more than a month after the first family's move to the White House, reports of strange happenings have continued to surface, with Sasha Obama confirming Tuesday that she had once again been visited by the eerie specter of the Bush twins.

The ghostly former first daughters, shortly after a White House elevator reportedly overflowed with cherry daiquiri.

Sasha, who was playing in the East Wing of the executive mansion so as not to disturb her busy father, reported seeing the former first twins while riding her Big Wheel tricycle down the Cross Hall corridor. The frightening apparitions, the 7-year-old said, emerged out of thin air and were dressed in identical outfits consisting of spaghetti strap tank tops and denim skirts.

"At approximately 4:36 p.m., we received a detailed account from Sasha Obama about a series of manifestations in the White House," press secretary Robert Gibbs announced. "However, a thorough search conducted by security officials has thus far uncovered nothing."

Added Gibbs, "Whatever grotesque and haunting images the president's youngest daughter thought she saw must have been a figment of her imagination."

This 209-year-old mansion is said to be haunted by the spirits of administrations past.

According to White House security documents, Sasha told Secret Service agents that the ghostly twins spoke to her in unison and repeatedly beckoned her by chanting the phrases "come play with us," "come play with us, forever," and "Daddy's making fajitas."

White House officials, speaking on condition of anonymity, also detailed a disturbing vision experienced by Sasha, who at several points during her encounter suddenly saw the twin girls lying motionless in a pool of spilled strawberry margaritas.

"She said they kept whispering 'we want to party' over and over again," said one Secret Service agent, who comforted Sasha following the incident. "God, it's so horrifying."

With her father often tied up with work for hours on end, this is not the first time Sasha has reported seeing malevolent spirits while exploring the 132-room mansion. Earlier this week, the 7-year-old was startled to find an angry, silver-haired woman named Barbara in the Map Room, and on Monday, the first daughter saw what appeared to be former attorney general John Ashcroft lying naked and unconscious in a bathroom tub.

As disturbing as her encounters have been, Sasha claimed that the sounds of incessant typing emanating from the Oval Office in recent days are what worry her the most.

While some White House staffers believe the visions to be nothing more than a child's plea for attention, others are less skeptical, claiming that the building's last resident committed horrible atrocities.

"There's just something about this place—maybe it's the long hours spent isolated in the Oval Office—but it gets into a man's head and eventually becomes too much to bear," White House gardener Emery Canter said. "We don't like to talk about what happened around here with the last occupant. We just want to put those bad memories behind us."

Though the president remains unconvinced by his daughter's wild stories, similar sightings have recently surfaced from other members of the White House staff.

"I had just walked into  the Red Room to clean it, when right in front of me I saw the twins exactly as I remembered them," said Rita Wesson, a maid who has worked at the White House for three administrations. "They were slouched down in their favorite chairs, and they had their feet up all over the antique furniture."

Added Wesson, "At first I wasn't sure it was them, but then Jenna yelled at me to get the fuck out."

President Obama this week issued a statement dismissing allegations that the White House is haunted, and has turned down several of the first lady's requests to move, saying that he finally has the chance to get some work done now.
