Since mid-February, the University of Pittsburgh has received more than 50 bomb threats, and while they've all been false alarms, they have succeeded in disrupting campus life. Tighter security measures are now in place, but the threats continue, and students are wondering how they'll be able to make up class work and prepare for final exams.
The Philadelphia Police Department is adding a new tool to its crime-fighting arsenal — Twitter. Supporters say the real-time information-sharing could help police build a stronger rapport with residents and better protect them.
West Philadelphia resident Mike Van Helder remembers when police knocked down his neighbor's door at 6 a.m. "There was shouting and loud noises and of course I didn't know what it was about," Van Helder recalls. "And them being my next door neighbors, I was understandably concerned."
Updated at 2:23 pm: Rick Santorum's daughter, Bella, is expected to be released from the hospital by Monday evening given the improvement in her condition, said Alice Stewart, spokeswoman for the former senator's campaign.
Assuming her release goes as planned and Santorum, who took a break from his campaign to tend to his daughter and for the Easter holiday, returns to the trail, that would clear the way for the Romney campaign to resume its negative advertising against Santorum.
There's a question whether Rick Santorum will prolong his presidential campaign to finish in Pennsylvania later this month. Mitt Romney, on the other hand, is moving in for the kill, buying $1.8 million of airtime in the state. NPR's Mara Liasson reports on the state of the GOP nominating campaign.
