2. A House divided

House Minority Leader Nancy Pelosi has been the face of House Democrats for more than a decade, but the events of the last month, including the upset primary victory of Alexandria Ocasio-Cortez in New York, has only emboldened those who are calling on leadership to clean house.

We ask ABC News' John Parkinson, who covers the House, if Pelosi or someone else will be leading the party in the fall.

3. The Challenger's survivor

The space shuttle Challenger explosion in 1986 was a tragedy, but a hopeful story emerged from the wreckage. A soccer ball survived the disaster and spent years hiding in a school's display case before eventually being sent into space for a second time.

ABC News' Bob Woodruff, who created a documentary about the ball for E:60, tells us why the story is so unfamiliar and what it means for future generations.

4. God Bless America

This year marks the 100th anniversary of "God Bless America," but you may not know the surprising history of the iconic song and the immigrant who wrote it.

Author Sheryl Kaskowitz tells us the story of the song: "What you think is going to be a simple symbol of patriotism ... is gonna be a bit more complicated than you think."
