A shortage of Adderall began last year, sending millions of people with attention deficit/hyperactivity disorder and narcolepsy on perpetual wild goose chases to find drugstores with the pills they need to stay alert and focused.

So it's not surprising that Adderall counterfeiters have seized a big marketing opportunity. What is surprising is their clumsiness.

In an interview with CNN, The Donald did not back down from his opinion that President Obama was not born in the United States.

CNN's Wolf Blitzer presented him with the overwhelming evidence that Obama was indeed born in Hawaii, but Donald Trump just raised his voice as he and Blitzer accused each other of sounding "ridiculous."

CNN calls it a "smackdown," and, indeed, it was a pretty contentious interview. Take a look:

The most potentially influential politician you've probably never heard of, former two-term Maine Gov. Angus King, on Tuesday officially entered the race to replace retiring moderate GOP Sen. Olympia Snowe.

King, 68, an alternative-energy entrepreneur and supporter of President Obama, filed more than 6,000 signatures with Maine's secretary of state to ensure his place on November's ballot.

He'll run as an independent, as he did for his successful gubernatorial runs in the 1990s.

On a recent Monday morning in Washington, D.C., a group of 3-year-old preschoolers bumbled their way into a circle, more or less, on the rug of their classroom. It was time to read.

The children sat cross-legged as their teacher, Mary-Lynn Goldstein, held high a book, Don't Let the Pigeon Drive the Bus. There was a short conversation about pigeons, then, for reasons that weren't entirely clear, cows; and then Goldstein began to read. She read as most teachers read, occasionally stopping to ask a question, point out a picture or make a comment about the story.

Facebook's stock fell $3.07 to end the day at $28.84. That's first time it's fallen below $30 since the stock went public.

That price is also 24 percent below its opening price of $38.

The Wall Street Journal that the drop had to do with negative sentiment about the stock, as well as the fact that today traders were able to trade on derivatives.

The Facebook stock saw so much trading, the Journal reports, that it triggered Nasdaq's short sale circuit-breaker.

Congress is considering legislation allowing the government to search through Internet traffic for early warnings of cyberattacks. The bills are controversial — worries about government surveillance have led to protests online.

The government does have a tool that could calm fears about this kind of legislation — it just doesn't use it.

America is the land of opportunity — that's the bedrock of the American dream. Many expect each generation to do better than the last.

That dream of economic mobility is alive and well for Pam Krank and her husband, Brian McGee. The two are proud owners of The Credit Department Inc., a successful business in the Minneapolis suburb of Mendota Heights.

"Mostly manufacturing companies around the world will hire us to study their customers and tell them how much ... unsecured credit they should grant to each customer," Krank explains.

At the moment the polls close in Texas Tuesday evening, most media outlets and very likely even the Mitt Romney campaign will declare that he has secured enough delegates to win the Republican nomination for president.

For what it's worth, there are two problems with that statement. First, as a practical matter, Romney actually won the Republican nomination when the other candidates competing for delegates in the primaries and caucuses stopped doing so. That was weeks ago.

Back in early April, a Philippine navy frigate tried to arrest Chinese fishermen accused of poaching sharks and giant clams.

But more is at stake than a boatload of seafood.

Neighboring countries say confrontations like this are growing as China asserts claims to territory well beyond its coastline. And analysts think China is testing America's resolve in the region.

Philippine officials say China still has more than 30 boats in the contested area, which is widely known as Scarborough Shoal, though the Chinese call it Huangyan Island.
