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.

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.

There are two war-related anniversaries this week that make today's album review all the more timely. Yesterday was Memorial Day here in the U.S.; tomorrow, May 30, marks 50 years since the world premiere of English composer Benjamin Britten's War Requiem at Coventry Cathedral. The War Requiem was commissioned for the cathedral's reconsecration after it had been destroyed by a Nazi bombing raid in 1940.

It's Tuesday and time to read from your comments. Cathy May(ph) in Bigelow, Arkansas heard our conversation about possible compensation for organ donors and wrote: I'm donating a kidney to a friend this coming August. While I don't care to be paid for donating, I would love to be reimbursed from my loss of salary while recovering from the process. It's a great honor to help another person, but it comes at a cost for me.

One of the day's most-discussed stories has to be The New York Times' report headlined "Secret 'Kill List' Proves A Test Of Obama's Principles And Will."

It's a long, detailed look at how the president has "placed himself at the helm of a top secret 'nominations' process to designate terrorists for kill or capture, of which the capture part has become largely theoretical."

Saying that each one of the recipients has touched countless lives, President Obama presented 13 Presidential Medals of Freedom during a ceremony in the East Room of the White House today.

All of the people on the stage, Obama said, "are my heroes individually." He said that if it were not for John Doar, the Justice Department official who personally escorted University of Mississippi's first black student to campus, he would not be president.
