The CNN Daily Mash-up is a roundup of some of the most interesting, surprising, curious, poignant or significant items to appear on CNN.com in the past 24 hours. We top it with a collection of the day's most striking photographs from around the world.
Donald Trump - you've heard of him, right? - told Republicans they need to be "mean as hell" against the Democrats in this fall's campaign. He also talked about the challenges business titans such as himself and Mitt Romney can face when they wade into politics:
They've been tough. They've been competitive. They work. They built their business. And honestly, they have left people in their wake, and they've made enemies. ...
They can't really go out there. They can't put it together because all of those people that they beat consistently over a lifetime ... all of those people come back to haunt (them).
The parents of 4-month-old Paul Sennert must keep an oxygen machine running to keep him alive, but the Woodward, Iowa, family fell behind on their electric bills. When viewers of CNN affiliate KCCI in Des Moines got wind of the Sennerts' dilemma, they stepped up big-time. The family's account with the electric utility has gone from $270 in the red to $1,400 in the black, with that much more on hand to help defray medical bills.
CNN iReporter Michael Black met space pioneer Neil Armstrong at a NASA celebration in April. He describes Armstrong as humble, funny and informative.
"One of the people at my table asked him, 'What are your thoughts about your fame?' and he said, 'I don't deserve it,' " Black recalled.
Black said watching Armstrong's Apollo 11 moon landing inspired him to become a science teacher.
"When I was 10 years old, everyone wanted to be firefighters, policemen or astronauts. Apollo gave teachers the opportunity to say, 'This is what is possible' to students," he said.
Black said he is sad that Armstrong's death faded quickly from the headlines.
"He is one of the most famous people who will ever live," Black said. "Five hundred years from now, so much of history will be forgotten, but people won't forget about Neil Armstrong and Buzz Aldrin walking on the moon."
A "swarm" of hundreds of small earthquakes near the California-Mexico border Sunday didn't do much harm, but it did inspire some spirited exchanges among CNN.com users, including this amusing one aimed at comment-thread trolls:
Quick!! Relate this to politics and blame a political party!
These earthquakes are clearly being caused by the massive debt (illustrated by a large bag of money) that California owes, sitting on the left side of the state and therefore causing the earthquakes.
No, saving the hurricane heading to New Orleans for that!
