It's the end of an era at ABC News. The New York Times reports that longtime ABC President David Westin has told staffers he will only remain at his post until the end of this year. According to one staffer, Westin will address his employees Tuesday and announce his departure. Sources say that the financial status of the news division was a divisive issue for Westin and ABC parent company Walt Disney; top management pushed Westin to turn the news division into a profitable venture but he was unable to do so. ABC's news programming trails NBC's, and earlier this year ABC slashed 25 percent of its workforce.
