How mapping America's "firearm ecosystem" could help lead to gun violence solutions
CBSN
On April 16, 2007, about a year after Maurizio Porfiri moved to New York City to start his career as an engineering professor at New York University, one of his undergraduate students rushed into his office, desperate, saying, "Professor I'm really sorry."
At first, he didn't know what was going on, but then Porfiri saw on the news there had been a mass shooting at Norris Hall, Virginia Tech's engineering science and mechanics building, where he had received his doctorate and spent seven years studying in the department.
"I started calling people, but no one would reply. It was a disaster," Porfiri told CBS News. Porfiri was a teaching assistant for Liviu Librescu, the engineering professor who blocked the door to his classroom to allow students to escape out the window. Another of the professors in his Ph.D. committee was also among the 32 people killed that day, as were other colleagues and classmates who helped Porfiri become who he is "personally and professionally," he said.

More employees of the Environmental Protection Agency were informed Wednesday that their jobs appear in doubt. Senior leadership at the EPA held an all-staff meeting to tell individuals that President Trump's executive order, "Ending Radical and Wasteful Government DEI Programs and Preferencing," which was responsible for the closure of the agency's Diversity, Equity, and Inclusion office, will likely lead to the shuttering of the Office of Environmental Justice and External Civil Rights as well.

In her first hours as attorney general, Pam Bondi issued a broad slate of directives that included a Justice Department review of the prosecutions of President Trump, a reorientation of department work to focus on harsher punishments, actions punishing so-called "sanctuary" cities and an end to diversity initiatives at the department.

The quick-fire volley of tariffs between the U.S. and China in recent days has heightened global fears of a new trade war between the world's two largest economies. Yet while experts think the battle is likely to escalate, they also say the early skirmishes offer hope for an agreement on trade and other key issues that could head off a larger conflict.
