A decade after the financial crisis, The Wall Street Journal has checked in on dozens of the bankers, government officials, chief executives, hedge-fund managers and others who left a mark on that period to find out what they are doing now. Today, we spotlight former Treasury Secretary Timothy Geithner and former Attorney General Eric Holder.

Eric Holder has gone from serving as the nation’s top prosecutor to being one of the business world’s leading advisers.

He was sworn in as U.S. Attorney General in February 2009 as policy makers were straining to support financial markets after the collapse of Lehman Brothers a few months earlier.

Under his leadership, the Justice Department negotiated several billion-dollar settlements for fraud tied to the mortgage market. But Mr. Holder has faced criticism for not prosecuting anyone on Wall Street for their roles in the financial crisis.

He stepped down in 2015 to return to Covington & Burling LLP, a Washington law firm known for representing banking clients where Mr. Holder is part of a unit charged with internal corporate investigations.
