Rachel Maddow reports on the planning of a massive protest event called "No Kings" scheduled for Saturday, June 14th, overshadowing Donald Trump's theatrical military parade, and marking a new peak in anti-Trump activism.

Officials in Parker, Colorado, denied a permit for a planned "No Kings" anti-Trump rally after the organizer was told it conflicted with the town's annual Parker Days festival, according to a report from local television station CBS Colorado.

Protests are taking place in Florida, nationwide on June 14 to object to President Trump's alleged birthday plans to celebrate with a military parade.

Pennsylvania Gov. Josh Shapiro said his team is ready for the "No Kings" march and rally in Philadelphia on Saturday. He urged participants to protest peacefully.
