 Call for a review of security preps for the Republican convention that starts tomorrow. Wisconsin Republican Party Chairman Brian Schimming. I feel really good about the security situation here in Milwaukee. I don't anticipate any major changes with it.

As you'd expect after the event yesterday, we've seen an uptick in social media chatter.
