The news of Justice John Paul Stevens's retirement wasn't even an hour old when Americans United for Life put out a warning to President Obama over his next Supreme Court nominee.

At 11:26 a.m., the group e-mailed a statement from its president and CEO, Dr. Charmaine Yoest, pledging "vigorous" opposition to Stevens's proposed replacement if the nominee doesn't suit the group's liking, and warning that some members of Obama's purported short list have a "radical track record on the abortion issue."

Here's Yoest's statement, in its entirety:

There are several nominees on the President's short list of replacements for Justice Stevens who have a radical track record on the abortion issue. If a nominee is selected who is committed to imposing his or her social agenda on the Court, rather than interpreting the Constitution fairly, we will work to oppose their confirmation vigorously.
