Lawmakers take scores of overseas trips each year to visit military bases, meet foreign officials, attend conferences and see how U.S. funds are spent. Ever since a corruption scandal in 2005 led to restrictions on privately funded travel, legislators have been taking more trips paid for by the government.
The cost they reported for such travel abroad was $13 million in 2008, a 70% jump from 2005, according to a Wall Street Journal analysis of travel records. Lawmakers don't have to report the cost of domestic travel when the government pays. The $13 million didn't include the expense of flying on Air Force planes, which lawmakers don't have to disclose.
