Latest On Orlando LGBT Night Club Mass Shooting

With guest host Jane Clayson.

After the worst mass shooting in U.S. history, we'll have the latest news from Orlando and expert analysis.

The massacre this weekend in Orlando, Florida is many things: it’s the deadliest in America’s long list of shooting rampages. To ISIS, it is the most successful terror strike on U.S. soil since 9/11. To this country’s gay community, it is an emotionally-shattering expression of homophobia. To law enforcement, it’s the crime it can’t anticipate or prevent. This hour On Point, the massacre in Orlando. — Jane Clayson
