A spokesman for Sen. Jeff Sessions, R-Ala., says the documents that the Senate Judiciary Committee has received from an advocacy group that Sonia Sotomayor once belonged to raise "several red flags, including a link between [LatinoJustice] PRLDEF and ACORN."

A statement released today by Sessions' office said the committee should have received these documents last week instead of Tuesday evening, and they amount to about half the material that the White House reviewed -- and a sliver of what's available. Sessions is ranking member of the Judiciary Committee.

"What we have now is just the tip of the iceberg," Sessions' office said. "We know that more than 300 boxes remain and their contents have not been shared with the committee....

"If these dilatory tactics continue, it will be increasingly more difficult for the hearing to go forward on July 13."
