Michael Hirsh is the latest editor to leave Newsweek following its takeover by Sidney Harman. Hirsh will be joining the National Journal as chief correspondent.
Newsweek has seen a series of editorial resignations announced since Harman agreed to buy the magazine from the Washington Post earlier this month.
Jon Meacham, chief editor, said he would leave after the acquisition is completed. Fareed Zakaria, editor of Newsweek International, announced his jump to Time Inc last week.
Newsweek's editor at large, Evan Thomas, who has been with the magazine for about a quarter of a century, also announced his departure.
Others known to be leaving the magazine include investigative journalist Michael Isikoff, editorial director Mark Miller, and digital executive editor Gabriel Snyder.
