"Pennsylvania lawmakers held a joint session of the state’s General Assembly to remember the victims of the Pittsburgh synagogue attack. The memorial on Wednesday came a day after the city’s mayor signed into law new gun control legislation introduced in the aftermath of the Oct. 27 shooting by a white supremacist that killed 11 worshippers.... Under the legislation, the AR-15 assault-style rifle used by the synagogue gunman would be banned."
