It’s happened again: A powerful, famous man is accused of improper, even criminal, sexual behavior and says he's seeking therapy to deal with it. "Guys, I'm not doing OK," Hollywood mogul Harvey Weinstein said Wednesday in a video licensed to NBC News. "I'm trying. I've got to get help."

"I support her decision," Weinstein said in a statement. "I am in counseling and when I am better, we can rebuild." Weinstein's spokesperson said he had begun counseling — without saying where or what kind — and "has listened to the community and is pursuing a better path." "Mr. Weinstein is hoping that, if he makes enough progress, he will
