Authorities have arrested a woman who the FBI says may have stolen a laptop computer or hard drive from House Speaker Nancy Pelosi's office during the Capitol riot earlier this month. The bureau says it is investigating whether she planned to funnel the device to Russia's foreign intelligence agency.
Riley June Williams, a Pennsylvania woman, was arrested on Monday in her home state on charges related to the Jan. 6 breach of the U.S. Capitol, including entering a restricted building, disrupting the orderly conduct of government and engaging in disorderly or disruptive conduct.
However, a complaint/arrest warrant from Sunday says the FBI is investigating a claim that Williams stole a laptop or hard drive from the speaker's office. According to one witness, described as a former romantic partner of Williams, the accused "intended to send the computer device to a friend in Russia, who then planned to sell the device to SVR, Russia's foreign intelligence service."
The unidentified witness said "for unknown reasons" the plan fell through and that Williams "still has the computer device or destroyed it."
"This matter remains under investigation," the FBI said.
In the days following the attack — in which rioters ransacked the speaker's office and ripped a name plate from above her door — Drew Hammill, Pelosi's chief of staff, confirmed in a tweet that a laptop "only used for presentations" had been taken from a conference room in the speaker's office.
The speaker's office told NPR Monday that it declined to comment on the court filing.
Sunday's complaint provides a link to a documentary filmed and produced by the London-based ITV News that includes footage shot inside the Capitol as the rioters streamed in. At about 20:40 into the video, a woman in glasses, wearing a green shirt and brown trench coat and carrying a black-and-white bag over her shoulder, identified as Williams, can be seen yelling "upstairs, upstairs, upstairs," pushing and urging people in the general direction of Pelosi's office.
The documentary singles out the woman, saying she was "disciplined, focused, with a sense of urgency, directing people up a staircase."
The same woman can be seen in other video taken outside the Capitol building on Jan. 6, according to the affidavit.
The FBI says Williams' mother filed a report with police in Harrisburg, Pa., about a suspicious person on Jan. 11 but that when officers interviewed her, Williams herself was not present. The suspicious person "was assumed" to be the same witness who had alleged Williams intended to sell the stolen laptop or hard drive, the bureau says.
"According to the Harrisburg officers, on January 16, 2021, they again spoke with WILLIAMS' mother who told them that a British media crew had come to her home the night before, asking to speak with WILLIAMS, who was not present. The news crew presented WILLIAMS' mother with one or more images taken at the U.S. Capitol on January 6, 2021. Her mother acknowledged that it was WILLIAMS in the image," the complaint says.
In a separate ITV News segment posted Jan. 16, the documentary crew interviews Wendy Williams, who identified herself as the mother of the woman in the video and confirmed that the video showed her daughter. In the segment, the mother says that her daughter is not home.
More than 125 people have been arrested so far in connection with the attack on the Capitol, on charges from curfew violations to federal felonies, according to The Associated Press.
