White House Counterterrorism Adviser John Brennan has given the most extensive justification so far for the US’s use of unmanned drone strikes against the suspected terrorists. The strikes have been controversial because they can even target US citizens without * oversight. As NPR's Larry Abramson reports Brennan claimed the strikes were both legal and the most ethical way to prevent potential terrorist attacks. Speaking at a Washington DC think tank, Brennan launched into an extensive defense of the use of unmanned aerial vehicles to launch lethal(致命的) strikes. He said these attacks protected the lives of Americans and innocent civilians on the ground.

"It’s this surgical precision(精确), the ability with laser like focus to eliminate the cancerous tumor, called an al-Qaeda terrorist while limiting damage to the tissue around it. That makes so counterterrorism tool so essential.”

Brennan's speech is time to coincide with the one year anniversary of the killing of Osama Bin Laden on May 2nd of last year. The administration has been using the occasion to trumpet(鼓吹) what they say as successes in the fight against terrorism. Larry Abramson, NPR News Washington.

A federal judge has blocked a new Texas law that would have prevented Planned Parenthood clinics across the state from receiving state funds for health screening and contraception. NPR's Nina Totenberg reports the clinics do not provide abortions or provide abortion counseling, but the state cut off their funding because they are affiliated(隶属于) with separately funded Planned Parenthood clinics that do.

Judge Lee appointed by President George W. Bush said that a new state law enacted by a republican dominated legislature would likely violate the First Amendment rights of Planned Parenthood Clinics by denying them funding because of their affiliation with those who advocate and perform abortions that he said would appear to be a clear violation of the First Amendment guarantee to freedom of expression and association.

Diplomatic ties between the US and China are being tested by news that the US embassy is giving refuge to a blind Chinese activist who had escaped house arrest. In Washington, President Obama would not comment on the matter specifically other than to say that the issue of human rights remains at the forefront of US-China discussions.

"Every time we meet with China, the issue of human rights comes up. It is our believe that not only is that the right thing to do because it comports(相称) with our principles and our believe in freedom and human rights, but also because we actually think China will be stronger.”

The president spoke during a joint news conference with Japan's prime minister.

A federal judge had dismissed a lawsuit against Three Cups of Tea author Greg Mortenson. Four readers of his besting selling book about efforts to build schools in Pakistan claim that the author defraud(欺骗) them by making up some of the story. NPR's Pam Fessler has details.

US Statistic judge Sam Haddon dismissed the suit against Mortenson and his publisher the Penguin Group as imprecise, flimsy(轻薄的) and speculative. The suit was brought after news reports that Mortenson fabricated(捏造) parts of the book, including that he was kidnapped by the Taliban. Defendants had sought refunds for all those who purchased the best seller. Mortenson used his book to help raise millions of dollars for his charity, the Central Asia Institute, which helps build schools in Pakistan. Earlier this month, Mortenson agreed to pay the charity one million dollars, after Montana’s Attorney General found that the author had mismanaged the group's funds. Pam Fessler, NPR News.

One World Trade Center under construction since the twin towers were destroyed in the 9.11 terror attacks. Now edges up the Empire State Building is the tallest in New York City. Workers raise a steel column to the top of the building today, putting it just over 1,250 feet. But Patrick Foye, Executive Director of the Port Authority of New York and New Jersey says there is much more to the skyscraper than meets the eye.

What we build is not only the tallest skyscraper in New York, it is a tower that will be the safest and most secure in the world, one that will also be the environmentally sustainable office building of its size anywhere.

The building is not done, floor are still being added. It's not expected to reach its full height for at least another year.
