WASHINGTON — In an expected development, White House Communications Director Anita Dunn is stepping down after a brief tenure marked by a dust-up with Fox News Channel over its coverage. She will be succeeded by her deputy, Dan Pfeiffer.
Dunn joined the administration in the spring with the understanding that she would stay only a few months because of family considerations. In her time with the Obama administration, she came to epitomize a more combative White House approach in dealing with critics.
She advocated a "rapid response" to counteract charges that she deemed to be meritless. She also pushed for President Obama to do more interviews, said an administration official who asked not to be named when discussing strategy.
Pfeiffer, a veteran of Obama's 2008 campaign, also favors using aggressive means to communicate the White House message.
Dunn declined to comment on her departure. Her work was largely behind the scenes, but she found herself in the headlines when she asserted that Fox was not a traditional news-gathering operation.
