U.S. Attorney Preet Bharara has had his share of big weeks since taking office nearly five years ago. But even for him, one week this month was a doozy.

Bharara netted his 79th straight insider-trading conviction on Feb. 6, securing a guilty verdict against former SAC Capital Advisors portfolio manager Mathew Martoma. His office started the week with a record-breaking False Claims Act settlement against a bank, inking a $614 million deal to resolve allegations that JPMorgan Chase & Co. duped two government agencies about loans that it underwrote or originated.
