President Trump is hosting a campaign-style Make America Great Again rally in Phoenix tonight, where he will address some of his most enthusiastic supporters. But there will also be various protestors and anti-Trump groups outside of the convention center ahead of tonight's event.

Why it matters: From Charlottesville to Boston, the past two weeks have put the tense protests between white nationalists, free speech advocates and anti-racism counter protesters on full display. Tonight is an opportunity to address Trump country in a way that was successful for him throughout the campaign, and a way that he clearly enjoys given the number of campaign-style rallies he has hosted since winning the election. But the trove of counter protesters expected tonight will serve as a reminder to Trump and the country that tensions have not been resolved and may be getting worse.
