Ex-Treasury Secretary Jack Lew joins private equity firm

Former U.S. Treasury Secretary Jack Lew has joined private equity firm Lindsey Goldberg as a partner.

• This means both Obama-era treasury secretaries are now private equity executives, as Tim Geithner previously joined Warburg Pincus as president.
• Middle market-focused Lindsay Goldberg is expected to be a fulltime job for Lew, although he'll remain as visiting professor at Columbia University.
• Lew and Lindsay Goldberg CEO Alan Goldberg both live in the same town (Riverdale, N.Y.).
