( EW.com ) -- ABC News President David Westin will resign his post after 13 years of service . He sent an email to staffers Monday that said while `` we 've put in place news anchors on all of our programs '' over the last nine months , the division also `` went through a very difficult transformation made necessary by changes in our business and its economics . '' One news report says that Westin , 58 , had a long-running feud with parent company Disney over making the division more profitable . Though ABC News has made significant gains over the last year -- Diane Sawyer has maintained respectable ratings on World News while Nightline has managed to flourish in late night opposite the talk shows -- it continues to rank No . 2 behind NBC in the mornings and evenings . Westin joined the division in March of 1997 and will remain its chief through the end of the year while ABC/Disney TV Group President Anne Sweeney finds a replacement . Sweeney released this statement Monday : `` For the past 13 years , David Westin has proved himself a tireless advocate for ABC News , effectively guiding the group through some of the most seismic industry , and divisional , changes imaginable . During that time , he helped reinvent our news organization , and positioned us for great success going forward . I 'm certain David will be as successful in whatever future endeavors he chooses to pursue . I will be announcing a new President of ABC News in the near future .
