IsikoffFirst on TVNewser: This is Michael Isikoff‘s last day at NBC News, TVNewser has learned.

Isikoff joined NBC News in 2010 as a Washington, DC-based investigative correspondent, after 16 years with Newsweek.  The news comes three months after fellow NBC News investigative reporter Lisa Myers left the network, and just two weeks after NBC hired Cynthia McFadden away from ABC, naming her senior legal and investigative correspondent.

“Michael has done terrific work for NBC News on stories ranging from revealing which government official leaked the US Stuxnet virus attack on Iran’s nuclear program to a groundbreaking examination of the Obama Administration drone strike program,” Richard Esposito, senior EP for NBC News’ Investigative Unit, tells TVNewser. “We’re grateful for all he’s done and wish him the very best.”
