The world’s largest private equity firm hired Senate majority leader Chuck Schumer’s (D-NY) son-in-law as a lobbyist around the time Schumer announced a deal that would have marginally limited a tax loophole enriching private equity moguls, before reportedly dropping the planned tax altogether.

The hire spotlights the network of Schumer’s family and former staff with ties to major companies with legislative business before the upper chamber run by Schumer.

Indeed, Schumer’s relatives and former staffers are now lobbying for the Blackstone Group, Amazon, Intel, and Google, among other corporate giants — all of which have been lobbying on pending Senate legislation.
