A Planned Parenthood clinic is seen in Vista, California, August 3, 2015. Planned Parenthood will be the focus of a partisan showdown in the U.S. Senate on Monday, as abortion foes press forward a political offensive against the women's healthcare group over its role in fetal tissue research. Congressional Republicans are trying to cut off Planned Parenthood's federal funding, reinvigorating America's debate about abortion as the 2016 presidential campaign heats up.     REUTERS/Mike Blake
