FILE - In this Feb. 11, 2015 file photo, Vice President Joe Biden listens as President Barack Obama speaks about the Islamic State group, in the Roosevelt Room of the White House in Washington. Biden faces the daunting decision of how and when to re-enter public life after burying his 46-year-old son. On Wednesday, Biden returns to Washington for lunch with the president and a meeting with the Ukrainian leader, but he'll head straight back to Wilmington, evoking memories of the nightly trips home that Biden took after he lost his first child decades ago at the start of his political career.
