Biden to Deliver Speech at Harvard

Vice President Joe Biden is planning to deliver a speech at Harvard University's Kennedy School of Government in Cambridge, Massachusetts, highlighting America's role in the world.

The speech is being billed as a chance for Biden to discuss "the opportunities and challenges posed by the rapidly changing international environment and discuss the administration's strategy for ensuring effective American leadership in the 21st century."

The speech comes as the Obama administration has faced a slew of international challenges including foreign conflicts between Russia and Ukraine, and Israel and Gaza - and the escalating military campaign in Iraq and Syria against Islamic State extremists.

Earlier in the day, Biden is planning to attend an event at a Boston restaurant for the Democratic National Committee.

The speech is scheduled to begin at 6 p.m.
