Elon Musk is leaving his role as the guiding force behind the Department of Government Efficiency initiative Friday after facing legal setbacks, clashes with Cabinet members and little evidence to support claims of savings or government efficiency.

Musk joined President Trump for a final press conference in the Oval Office on Friday afternoon, capping a 130-day tenure that also saw Musk face rising unfavorability numbers, financial stress on his business empire and a rift between the world's richest man and its most powerful political leader.

The president, appearing to largely read notes from a binder, offered praise for Musk's work as "one of the greatest business leaders and innovators the world has ever produced."
