Earlier today, Sen. Orrin Hatch (R-UT) called in to MSNBC to raise concerns about a judge whom he's supported twice.

Hatch cites, among other things, an article Sotomayor wrote in 1996--two years before he supported her confirmation to the Second Circuit Court of Appeals. But, he says, the Supreme Court is a different thing altogether.

As a senior, and influential, member of the Judiciary Committee, Hatch will have significant sway over how quickly and smoothly the coming confirmation process moves forward.
