Excerpt:
A Texas teenager who was suspended from school for bringing a homemade clock to class received a 21st century invitation from President Obama on Wednesday to visit the White House.
Instead of making a traditional phone call, Obama took to his personal Twitter account to invite Ahmed Mohamed, 14, of Irving, Texas, to show off the device at 1600 Pennsylvania Ave.
"Cool clock, Ahmed. Want to bring it to the White House? We should inspire more kids like you to like science. It's what makes America great," the president tweeted.
