• 'Stand your ground' trial begins. Jury selection is due to start in the case of Michael Drejka, the Florida man who shot dead Markeis McGlockton during a 2018 argument over a parking space. Testimony is sure to touch on the state's self-defense law and the heavy burden it puts on prosecutors.
• Tucker Carlson returns to the airwaves. The Fox News host is due back after he took what the network said was a previously planned vacation just after falsely telling his viewers that the nation's white supremacy problem "is a hoax."
• Observe World Humanitarian Day. Explore ways to help those in need with CNN's Impact Your World. We know it can feel impossible to make a dent in the world's massive pile of problems, but a little aid can go a long way.

• US Secretary of State is expected at the UN. Mike Pompeo is reportedly expected at the United Nations Security Council gathering in New York. The group is set to debate Middle East security.

Cummings hosts a forum on child trauma, a problem that impacts kids nationwide.
• America observes 400 years since slaves arrived. This marks a dismal day in our history, when a Dutch ship carrying 20 enslaved Africans landed in Jamestown, Virginia. Four centuries later, the horrid practice's roots still shadow our culture and our politics, including the ongoing debate about whether reparations still are owed.
