One week before Supreme Court nominee Elena Kagan begins her Senate confirmation hearings, both liberal and conservative groups are criticizing her record on abortion rights.

The anti-abortion group Americans United for Life, which calls Kagan a pro-abortion activist, recruited failed conservative Supreme Court nominee Robert Bork for a news teleconference this week to denounce her. At the same time, the liberal Center for Reproductive Rights released a report Monday casting doubt on the depth of Kagan’s support for abortion rights.
