Journalist Mark Halperin, who was accused of sexually assaulting several women, is trying to get back into the news business.

Halperin began tweeting April 10 for the first time in a year-and-a-half and has launched a blog to weigh in on political news of the day, “Wide World of News” — a play on the 1970s weekend show “Wide World of Sports” aired by ABC, where Halperin was political director for a decade.
