BOSTON – President Barack Obama's aunt buried her face in her hands and sobbed as she described her anguish over no longer having contact with him and his family after the revelation she had been living illegally for years in the United States in public housing.

Zeituni Onyango (zay-TUH'-nee awn-YAHN'-goh) told The Associated Press in an exclusive interview that she is troubled that her immigration woes have made her a political liability to her nephew.

Onyango, the half sister of Obama's late father, said she has exiled herself from the family after attending Obama's inauguration because she didn't want to become fodder for his foes. Obama and his family have not reached out to her either, she said.

"Before, we were family. But right now, there is a lot of politics, and me, I am not interested in any politics at all," said Onyango, whose appeal for asylum from her native Kenya is before an immigration judge in Boston.

The Obamas are her only family in the United States, she said.
