The Secret Service says a woman is under arrest and in the custody of District of Columbia police after jumping over the White House fence on Wednesday.
A Secret Service spokesman identified the woman, who wore an orange jumpsuit, as Diane Wilson. She was charged with unlawful entry and handed over to local authorities.
No hometown was given for Wilson. She appeared to be among a group of 17 similarly attired demonstrators who had chained themselves to the fence on the northwest side of the White House.
They were protesting the detention of terrorist suspects at the U.S. prison at Guantanamo Bay, Cuba.
President Barack Obama was not in the White House at the time. He has said he is redoubling his efforts to close the Guantanamo facility.
