President Donald Trump has nominated Nicola Hanna to head the Los Angeles U.S. Attorney’s Office, the nation’s second-largest federal prosecutor’s office behind only Washington, D.C. Hanna was among a group of five U.S. attorney nominees the White House announced Friday.

Hanna was a white-collar partner at Gibson, Dunn & Crutcher’s Irvine and Los Angeles offices prior to being named interim U.S. attorney for the U.S. Attorney’s Office for the Central District of California last month by U.S. Attorney General Jeff Sessions. At the firm, he recently helped handle Apple Inc.’s antitrust case accusing Qualcomm Inc. of abusing its market dominance over baseband processor chips to leverage outsized royalties for its technology.
