Apparently, the two are being considered these days, as Jesse J. Holland reports for the Associated Press.

If there is a Supreme Court vacancy this summer, President Bush may look no farther than the Capitol for a member of Congress who can be confirmed quickly. Past presidents have done it, more than two dozen times.

While admittedly long shots, GOP Sens. Jon Kyl of Arizona and John Cornyn of Texas are being talked up by some conservatives as possible nominees for the high court.

Seen as most likely to step down is Chief Justice William Rehnquist, who at 80 is fighting cancer. Retirement also might be attractive option for Justices Sandra Day O'Connor, 75, and John Paul Stevens, 85.

Kyl is a stalwart pro-business conservative and a senior member of the Senate Judiciary Committee. Cornyn is a former Texas Supreme Court justice and state attorney general. Both men have been at the forefront in fighting Democratic filibusters against Bush's federal appeals court nominees.

There is quite a history of legislators moving to the bench, though O'Connor is the only former legislator on this Supreme Court. It would be interesting to see how the nomination of Cornyn or Kyl would play out in the Senate -- whether it would be like Nixon's threatened nomination of the then conservative Robert Byrd or whether it would be smooth sailing.
