Federal travel and conferences: Spending down, as lawmakers consider more restrictions, Washington Post
"But the $1.1 trillion funding bill congressional negotiators unveiled Monday does attempt to put some restrictions into law, at least for the rest of the fiscal year. Agencies would have to submit reports to their inspector general on any conference that costs more than $100,000 and include the number of participants, the purpose and a detailed breakdown of food and other costs. Inspectors general also would need to be informed of conferences that cost more than $20,000. Agencies could not send more than 50 employees to an international conference, unless it involves law enforcement personnel."
