Since January, Hollander, who is affiliated with Musk’s so-called Department of Government Efficiency (DOGE), has been working on real estate projects related to federal leases and office buildings for GSA. The move is part of a purported wind-down for Musk and his leadership team at the so-called Department of Government Efficiency. Steve Davis, a longtime Musk lieutenant, is also reportedly leaving DOGE, according to the The Wall Street Journal. Hollander oversaw real estate projects for Twitter (now X), while Davis managed a brutal cost-cutting program known as zero-based budgeting. Since February, the GSA has been carrying out plans to prepare to sell hundreds of federal office buildings.
