WASHINGTON (CNN) -- President Bush on Tuesday selected U.S. Circuit Judge John Roberts Jr. as his nominee to replace retiring Justice Sandra Day O'Connor on the Supreme Court.
Bush called the selection of a nominee to the high court "one of the most consequential decisions a president makes."
The move sets the stage for a possible battle with advocacy groups who have criticized Roberts in the past.

Officials: Bush Chooses D.C. Circuit's John Roberts Jr. for Supreme Court
President Bush chose D.C. Circuit Judge John G. Roberts Jr. on Tuesday as his first nominee for the Supreme Court, selecting a rock-solid conservative whose nomination could trigger a tumultuous battle over the direction of the nation's highest court, senior administration officials said. Bush offered the position to Roberts in a telephone call Tuesday afternoon, in advance of his formal announcement in a broadcast speech to the nation.
I noted a discussion of Judge Roberts' potential nomination in a Legal Times article here on February 18th.
