ABC News, citing police sources, reports that Barbara Bush's purse was snatched at a Buenos Aires restaurant during a night on the town.
Secret Service agents did not notice.
Kim Bruce, spokeswoman for the Secret Service - which provides protection for the President and family - says, "we don't have any comment on that."
The White House did not immediately return telephone calls seeking comment.
Barbara, named after the President's mother, and her twin sister Jenna turn 25 on Saturday.
The twins were dining in San Telmo, Buenos Aires's picturesque arts and dining neighbourhood.
ABC News reports that the theft was not the only difficulty the Secret Service faced during the fraternal twins' two-week visit.
One of the agents got into an "altercation" after a night on the town and was beaten.
