Attorney General Michael Mukasey has taken personal trips on government jets almost every weekend since he took office less than a year ago at a cost to taxpayers of more than $155,800, Justice Department and Federal Aviation Administration travel records show. Mukasey took so many trips to his home in New York on FAA, FBI or Drug Enforcement Administration planes that he was outside Washington a third or more of February, May, July, August and September. From November 2007 to September 2008, he traveled to New York 45 times, according to the records, which were released in late October in response to open records requests that McClatchy filed nine months ago. Mukasey traveled with his wife on 17 of the trips, and eight of them were with four or five other relatives. Mukasey reimbursed the government a total of $15,246 for all of his trips, based on round-trip coach fares, as he's required to do by government travel regulations. However, the cost of operating the Gulfstream G5s, Cessna Citations and de Havilland Dash 8-100s that Mukasey uses is tens of thousands of dollars more. For example, the attorney general reimbursed the Justice Department $128.80 for a round-trip ticket to New York. The actual cost to the government, according to the department: $4,021.32. Mukasey's personal trips appear to outpace those of other officials who are required to travel on government jets. During the same time period, Defense Secretary Robert Gates took fewer than six personal trips, and he also reimbursed the government at coach fares.
