Zero in on Schlozman.

Remember him?

TPM:

Brad Schlozman, the former Justice Department official who left the Department in August 2007 after he openly admitted to "boasting" about his hiring of conservative Republicans, is the focus of a new turn in the DOJ's investigation into the 2006 U.S. attorneys firing scandal.
The Wall Street Journal reports today that lawyers have filed for a grand jury referral, which could lead to criminal charges, in order to investigate Schlozman's involvement in improper prosecutions during his time running the DOJ's civil-rights division in general. The referral appears specifically tied to possible perjury in his 2007 congressional testimony.

The Journal, summarizes Schlozman's past role in the investigation:

In testimony before the Senate Judiciary Committee, Mr. Schlozman conceded boasting to associates about the number of Republicans he managed to hire at the department. The allegations against him helped feed months of scandal that eventually forced the resignation of Attorney General Alberto Gonzales in August.

. . . At a Senate hearing last June, Democrats zeroed in on allegations that Mr. Schlozman was part of an effort by Republican political officials to pursue vote-fraud investigations in important swing states as a way to gain electoral advantage.

Mr. Schlozman's promotion to the U.S. attorney's office in Kansas City came after the department asked his predecessor, Todd P. Graves, to resign. Mr. Graves was among several U.S. attorneys who had shown reluctance to bring vote-fraud-related cases, according to testimony and documents gathered by Senate investigators last year.

After Mr. Schlozman's arrival in Kansas City, prosecutors filed charges against workers from a left-leaning activist group, Acorn. The workers eventually pleaded guilty to violations related to voter registration. The timing of the indictment, five days before a close Senate election, drew criticism from Democrats.
