Here's your daily look at five stories we're following:
1. Gay marriage lawsuit: The state has sued the Montgomery County register of wills to stop the county from giving marriage licenses to same-sex couples. A county lawyer, however, says Montco will continue to issue the licenses while the litigation proceeds.
2. Transgender violence: Police are investigating the Tuesday-night shooting of a transgender woman in a Northern Liberties apartment. The motive for the attack is unknown, but the shooting come shortly after another transgender woman was slain and dismembered after a man picked her up for a sexual encounter. That slaying spurred a vigil in LOVE Park and calls to stop violence against transgender people.
3. Voter ID closings: After nearly three weeks of testimony, closing arguments are expected today in the trial over the constitutionality of Pennsylvania's voter identification law. Meanwhile, U.S. Sen. Bob Casey weighed in on the law Tuesday, saying the measure was politically motivated.
4. Gas explosion investigated: Officials are continuing to probe the South Philadelphia gas explosion that destroyed three rowhomes and injured eight people. Mayor Nutter says the work being done on the recently renovated home where the blast occurred had passed inspections, and it would be "pure speculation" to say a contractor's cigarette ignited the explosion.
5. Sports round-up: The Phillies beat the Giants, 7-3, to end an eight-game losing streak Tuesday night. The teams play again today at Citizens Bank Park at 7:05 p.m. It's day 10 of Eagles training camp; the team practices at the NovaCare Complex at 12:30 p.m.
