While I normally get irked by her twitter outbursts, I applaud her for calling this guy out for touching her. That sort of behavior, especially among professional contacts is NOT okay, and Banks did the right thing by exposing him for that ****.
Most girls would be ashamed to do just that, either browbeaten or shamed by peers (which may be why she deleted the tweet) or intimidated into silence by the perpetrator. Even though the tweet has been deleted, plenty of people have already seen it.
