Here's your daily look at five stories to know about:
1. Liberty Medal ceremony: Hillary Rodham Clinton will receive the Liberty Medal at a ceremony tonight at the National Constitution Center. She had been slated to use the event for a speech on national security and privacy, but aides have said those plans are on hold due to the situation in Syria. Clinton announced her support on Monday for a U.S. strike in Syria, and is expected to reiterate her views tonight in Philadelphia. Clinton's appearance also puts a focus on a potential presidential bid in 2016, and supporters of the Ready for Hillary super PAC are slated to gather tonight in Northern Liberties to watch the speech.
2. Syria speech: Also set to speak on Syria tonight is President Barack Obama, who will address the nation at 9 p.m. The president will make his case for a U.S. military strike to the public. Meanwhile, a potential breakthrough came Monday, when Russia called on Syria to give up its chemical weapons supply and Syria's foreign minister appeared receptive.
3. Miss America: Preliminaries in the Miss America competition, making its return to Atlantic City this year, begin at 8 p.m. today. Prelims continue through Thursday and the pageant finale is Sunday.
4. Starvation death of 3-year-old: A 3-year-old West Oak Lane girl with special needs died Monday of starvation, and the city's medical examiner ruled her death a homicide. Late Monday night, Nathalyz's parents -- 27-year-old Carmen Ramirez and 30-year-old Carlos Rivera -- were charged with murder in the girl's death. Investigators are still determining who the child's primary caretaker was and how long she had been starved. Nathalyz's four other siblings are in the custody of the Department of Human Services and were being examined by doctors.
5. Judicial discipline: The Pennsylvania Supreme Court is scheduled to hear oral arguments today about disciplining judges. The court will decide whether the state's high court or the Court of Judicial Discipline can suspend judges for an interim period, and what happens if the two courts have conflicting decisions. The case before the court stems from the Philadelphia Traffic Court ticket-fixing scandal.
