Here's your round-up of five stories we're following today:

1. Lautenberg funeral, special election: Vice President Joe Biden will eulogize Sen. Frank Lautenberg at a Manhattan funeral service this morning. The New Jersey Democrat died on Monday. Hillary Clinton and fellow New Jersey Sen. Robert Menendez are also slated to speak. A ceremony at the Secaucus train station that bears Lautenberg's name is scheduled for this afternoon, and his casket will arrive at the U.S. Capitol on Thursday, before Friday's burial at Arlington National Cemetery. Meanwhile, Gov. Christie has set an Aug. 13 primary and Oct. 16 general election for Lautenberg's seat.

2. Germantown sex assaults: Police were questioning a man overnight in connection with armed sexual assaults on four teenage girls in Germantown. The attacks have put the neighborhood on edge.

3. N.J. governor's race turns to Christie-Buono: Republican Gov. Chris Christie and Democratic challenger state Sen. Barbara Buono won their respective primaries last night. After the low-profile primaries in which neither candidate faced an opponent who was a real threat, both sides are ramping up their general election campaigns.

4. Search for Delco mom: Police will canvas a Collingdale neighborhood this morning to search for clues in the disappearance of Melissa Otiz-Rodriguez, who vanished in mid-April.

5. Sebelius won't intervene for Sarah: Health and Human Services Secretary Kathleen Sebelius says other children are just as ill as 10-year-old Sarah Murnaghan, and she won't personally intervene in the Newtown Square girl's case. The Murnaghan family has launched a high-profile fight over organ-donor rules that say Sarah, who needs a lung transplant, can only recieve lungs from another child. Sebelius has asked for a review of the lung-donor policy.
