rights group is pulling an ad campaign that used the likeness of first lady Michelle Obama without her permission. People for the Ethical Treatment of Animals used photos of Mrs. Obama in an anti-fur campaign because the first lady does not wear fur. But they never received authorization from her. PETA also is urging the White House to take a stand against the Ringling Bros. circus, which last week debuted its newest performing elephant, “Baby Barack.” PETA says circus elephants are abused. Feld Entertainment, which owns the circus, says its elephants are well cared for and using the name Barack is intended as an honor.
