Mica, chairman of the House Transportation and Infrastructure Committee, spoke during a hearing Tuesday at the Georgetown West Heating Plant in Washington.
The representative also criticized the administration for spending $3.5 million to maintain a vacant heating plant, gone unused since 2000, that is scheduled to be auctioned in September.
Flavio Peres, GSA’s deputy assistant commissioner for real property utilization and disposal, said the agency has sold $4.2 billion worth of buildings and structures during the last decade.
GSA defended itself in a blog post, claiming it has cut $317 million in real estate costs this year.
