The Justice Department Office of Inspector General on Monday released a report ^[1] detailing excessive travel costs accrued by a handful of former leaders of U.S. Attorneys’ offices.

The Inspector General report says the five unnamed former heads “routinely exceeded the government rate [for lodging], by large amounts, with insufficient, inaccurate, or no justification” from 2007 to 2009. The ex-leaders served as acting, interim, court-appointed or presidentially appointed U.S. Attorneys.

Though unnamed, three of the former heads were men and two were women. One ex-leader, Chris Christie, is apparently listed as “U.S. Attorney C” in the report. Christie, now New Jersey’s governor and a possible Republican presidential candidate, was the state’s U.S. Attorney from 2002 to 2008.

“U.S. Attorney C” stayed at the Nine Zero Hotel in Boston, paying $449 per night, which is more than twice the government rate, according to the report. He also spent more than double the government rate at the Four Seasons hotel in D.C., paying $475 per night, the report said.

Christie stayed at the same hotels, according to a 2009 Talking Points Memo report ^[2] on the former U.S. Attorney’s excessive travel expenses. The governor didn’t respond to a request for comment from TPM at the time. His travel expenses became an issue ^[3] in his campaign last year against then-Gov. Jon Corzine (D).

In all, 19 U.S. Attorneys exceeded the government rate on 11 or more trips, the report said. These 19 top prosecutors submitted a total of 311 lodging reimbursement vouchers above the government rate.

Put another way, 40 percent of all trips in which the government rate was exceeded were taken by fewer than 10 percent of the 208 U.S. Attorneys reviewed, the IG said.
