U.S. Marines are on high alert. So are the CIA and the White House, for that matter.
Politicians on both sides of the aisle also are ready to enter the fray.
All the fuss is over the Senate Intelligence Committee's $50 million investigation of Bush-era CIA interrogation tactics on detainees in the years after the September 11, 2001, terrorist attacks.
The long-delayed report on the use of torture - "enhanced interrogation techniques" - by the U.S. government is expected to be released Tuesday morning.
This won't be a full disclosure, but the report's 480-page executive summary. There will also be a shorter Republican counter-assessment and the CIA's own assessment. The complete report totals more than 6,000 pages.
A man stabbed a student at a Brooklyn synagogue early Tuesday morning before he was fatally shot by an officer he lunged at, police said.
The man walked into the Chabad Lubavitch World Headquarters around 1 a.m., where students had been up late studying.
The victim, an Israeli named Levi Rosenblatt, was stabbed in the neck but his injuries aren't life threatening, Chabad Lubavitch said.
The attacker is believed to be homeless, CNN affiliate WABC said. It's not clear why he stabbed the 23-year-old student.
A twin-engine plane crashed into a house in a Gaithersburg, Maryland, subdivision on Monday morning, killing three people in the plane, and a mother and two small boys in the residence, according to local and federal authorities.
The bodies of Marie Gemmell and her sons, Cole, 3, and Devon, an infant, were found in the second-floor bathroom of one of the houses struck by the plane, said Pete Piringer, the public information officer for Montgomery County Fire and Rescue.
One of the people killed on the plane was Michael Rosenberg, CEO and founder of a North Carolina clinical development company called Health Decisions, according to a statement from the company. The flight originated in Chapel Hill, North Carolina, close to the company headquarters in Durham.
The crash occurred about 10:44 a.m. Monday as the twin-engine Embraer EMB-500/Phenom 100 made an instrument approach to Montgomery County Airport, Robert Sumwalt of the National Transportation Safety Board said at a press conference near the wreckage.
