The National Security Agency's internal watchdog detailed a dozen instances in the past decade in which its employees intentionally misused the agency's surveillance power, in some cases to snoop on their love interests.
A letter from the NSA's inspector general responding to a request by Sen. Chuck Grassley, R-Iowa, lists the dozen incidents where the NSA's foreign intelligence collection systems were abused. The letter also says there are two additional incidents now under investigation and another allegation pending that may require an investigation.
At least six of the incidents were referred to the Justice Department for possible prosecution or additional action; none appear to have resulted in charges. The letter doesn't identify the employees.
Several of the cases involve so-called "Loveint" violations.
Americans commemorated this week the loss of those who died at the hands of al Qaeda terrorists on September 11, 2001. Their leader chimed in a day later with new threats against the United States.
Ayman al-Zawahiri called on his followers in an audio message posted on the Internet on Thursday to "land a large strike on it, even if it takes years of patience for this."
Going it alone against the Syrian government is not what President Barack Obama wants, U.S. Secretary of State Chuck Hagel said Friday. Â But that scenario is looking more and more likely.
A day earlier, the United States' closest ally, Great Britain, backed out of a possible coalition. A U.N. Security Council meeting on Syria ended in deadlock, and in the U.S. Congress, doubts about military intervention are making the rounds. Â
Skeptics are invoking Iraq, where the United States government under President George W. Bush marched to war based on a thin claim that former dictator Saddam Hussein was harboring weapons of mass destruction.
A nuclear missile base in Montana that failed a safety test this month has let its security chief go.
The 341st Missile Wing at Malmstrom Air Force base operates about a third of the nation's Minuteman III nuclear missiles.
It did not relieve Col. David Lynch from his command over the security forces group because of the failure,Â the base said in a statement released this week. But missile wing commander, Col. Robert Stanley, will feel more confident about passing the next inspection without him.
Edward Snowden is in good health in Russia and his lawyer there is amenable to hammering out an ending that would satisfy all. This, according to his father's lawyer, Bruce Fein, who appeared on "Anderson Cooper 360" on Wednesday night.
He relayed the conversation he had with Russian lawyer Anatoli Cuchara.
"There may be a time, where it would be constructive to try and meet and see whether there can't be common ground that everyone agrees would advance the interest, the United States, Mr. Snowden, Lon, his father and the interest of Russia in trying to resolve this in a way that honors due process and the highest principles of fairness and civilization," Fein said.
Snowden is afraid he would not get a fair trial if he came back to the United States.
Washington is urging Moscow to send Edward Snowden back to the United States instead of letting him fly to Ecuador for asylum.
"We expect the Russian government to look at all options available to expel Mr. Snowden back to the U.S. to face justice for the crimes with which he is charged," U.S. National Security Council spokeswoman Caitlin Hayden said early Monday.FULL STORY
The parents of the Boston Marathon bombing suspects have left their home in Dagestan for another part of Russia, the suspects' mother Zubeidat Tsarnaev told CNN Friday. She said the suspects' father, Anzor Tsarnaev, is delaying his trip to the United States indefinitely.
He was to fly to the United States as soon as Friday to cooperate in the investigation into the attacks. But his wife called an ambulance for him Thursday.
She told CNN's Nick Paton Walsh that her husband was delaying the trip for health reasons. She wouldn't elaborate.
Anzor Tsarnaev agreed to fly to the United States after FBI agents and Russian officials spoke with them for hours this week at the family's home.FULL STORY
North Korea on Friday shunned a South Korean proposal for talks over the two countries' joint manufacturing zone, where Pyongyang halted activity this month amid tensions.
In a statement on state media, a spokesman for the North's National Defense Commission described Seoul's offer of talks about the Kaesong Industrial Complex as "deceptive."
The complex, which is on the North's side of the border but houses the operations of more than 120 South Korean companies, is seen as the last major symbol of cooperation between the two countries.FULL STORY
South Korea's government said Sunday it believes North Korea may test a missile around April 10, citing as an indicator Pyongyang's push for workers to leave the Kaesong Industrial Complex by then.
Seoul "is on military readiness posture," said South Korea's Blue House spokeswoman Kim Haeng in a briefing. She said national security chief Kim Jang-soo also based the assessment on North Korea's hint to foreign diplomats in Pyongyang to send personnel out of the country.FULL STORY
A former CIA officer who pleaded guilty in October to identifying a secret agent was sentenced today to 30 months in prison.
John Kiriakou and prosecutors agreed on the sentence length as part of the plea deal he entered into three months ago. In her Alexandria, Virginia, court, U.S. District Judge Leonie Brinkema said that she rejected the defense's attempts to characterize Kiriakou as a whistle-blower, and she would have sentenced the 48-year-old former agent to more time if he had been convicted at trial.

Former CIA Director David Petraeus testified on Capitol Hill on Friday that the attack on the U.S. Consulate in Benghazi, Libya, was an act of terrorism committed by al Qaeda-linked militants.
Rep. Peter King told reporters that Petraeus made an opening statement that took about 20 minutes and then answered questions for about an hour and 10 minutes.
King was one of the Republican and Democratic members of the House and Senate intelligence committees who heard from Petraeus about the September 11 attack that left four American dead, including U.S. Ambassador Chris Stevens.
Quazi Mohammad Rezwanul Ahsan Nafis was indicted Thursday on charges of attempting to use a weapon of mass destruction and trying to provide material support to al Qaeda in a foiled effort to blow up the Federal Reserve Bank in New York City.
Nafis - a 21-year-old exchange student - is accused of plotting to detonate a bomb outside of the bank in October.
Ex-CIA chief David Petraeus told HLN's Kyra Phillips that he did not share classified information with his mistress, Paula Broadwell, nor was his resignation tied to upcoming testimony on the attack in Benghazi that killed Ambassador Chris Stevens.
Here's how Phillips reported her interview on "Morning Express with Robin Meade" on CNN's sister network.
Former CIA Director David Petraeus will testify Friday before the House Intelligence Committee about the September attack on a U.S. diplomatic compound in Benghazi, Libya, the committee announced Wednesday.
Petraeus had been scheduled to testify before Congress this week, but his testimony was in question after he resigned last week as CIA director over an extramarital affair.
Paula Broadwell, whose affair with CIA Director David Petraeus led to his resignation, has had her government security clearance suspended pending the outcome of ongoing investigations, two U.S. officials with direct knowledge told CNN's Barbara Starr.
A U.S. official previously said that Broadwell, an Army Reserve officer, did have some kind of security clearance.
Petraeus resigned from his CIA director post last week after an FBI investigation revealed he had an extramarital affair, an investigation that also prompted questions about whether his paramour, Broadwell, had inappropriate access to classified information.
Investigators have found classified information on a computer belonging to Broadwell, a law enforcement source told CNN national security contributor Fran Townsend. It was not clear if this was a computer seized at her home Monday night or one she had previously given to authorities when she cooperated back in September.
Earlier, John Nagl, a retired military officer who worked for Petraeus for years, said that Petraeus insists he never shared classified information with Broadwell. He spoke to him via e-mail on Monday and was authorized by Petraeus to talk.
Check out this story for more details on the investigation.
Retired Army Gen. David Petraeus resigned from his CIA director post last week after an FBI investigation revealed he had an extramarital affair,Â an investigation that also prompted questions about whether his paramour had inappropriate access to classified information.
The scandal also has sparked an investigation into whether Marine Corps Gen. John Allen, the top U.S. commander in Afghanistan, sent inappropriate messages to a different woman, leading President Obama to put Allenâ€™s nomination to become NATOâ€™s supreme allied chief on hold.
FBI agents are at the Charlotte, North Carolina, home of Paula Broadwell, the woman who had an affair with then-CIA Director David Petraeus, said FBI spokeswoman Shelley Lynch.
Lynch declined to say what the FBI is doing at the house. Petraeus resigned as CIA Director last Friday, citing an extramarital affair as the reason.
Editor's note: Retired Gen. David Petraeus stepped down Friday as head of the Central Intelligence Agency - 14 months after taking the job, days after the presidential election and days before he was to testify before Congress about an attack on a U.S. consulate in Libya that left four Americans dead.
[Updated at 7:59 p.m.] Speaking on CNN's "Erin Burnett OutFront," Rep. Peter King (R-New York) called Petraeus' resignation "a real loss for the country, a real loss for the CIA."
"We're going to lose the best man for the job, but again America is adaptable," said the chairman of the House Homeland Security Committee. "Put it this way, anytime you lose a David Petraeus, the country is not as safe as it could be."
[Updated at 7:11 p.m.] The FBI investigated a tip that the woman Petraeus was involved in an extramarital affair with was Paula Broadwell, who co-wrote a biography about him, a U.S. official said.
Broadwell spent a year with Petraeus in Afghanistan, interviewing him for the book "All In: The Education of General David Petraeus."
CNN has not been been able to reach Broadwell for comment. It is not clear if Broadwell is the woman with whom Petraeus had admitting having an affair, leading to his resignation Friday as the head of the CIA.
Here is the full text of a letter ex-CIA Director David Petraeus sent to colleagues after he submitted his resignation to President Obama:
Central Intelligence Agency
9 November 2012
Yesterday afternoon, I went to the White House and asked the President to be allowed, for personal reasons, to resign from my position as D/CIA. After being married for over 37 years, I showed extremely poor judgment by engaging in an extramarital affair. Such behavior is unacceptable, both as a husband and as the leader of an organization such as ours. This afternoon, the President graciously accepted my resignation.
As I depart Langley, I want you to know that it has been the greatest of privileges to have served with you, the officers of our Nationâ€™s Silent Service, a work force that is truly exceptional in every regard. Indeed, you did extraordinary work on a host of critical missions during my time as director, and I am deeply grateful to you for that.
Teddy Roosevelt once observed that lifeâ€™s greatest gift is the opportunity to work hard at work worth doing. I will always treasure my opportunity to have done that with you and I will always regret the circumstances that brought that work with you to an end.
Thank you for your extraordinary service to our country, and best wishes for continued success in the important endeavors that lie ahead for our country and our Agency.
With admiration and appreciation,
David H. Petraeus
