Vice President Joe Biden discussed ways to end Iraq's political deadlock with Talabani, the country's president, in an effort to push leaders to bridge their differences, which have created a dangerous political vacuum. Talabani said the discussion focused on ways to move Iraq's political process forward after March's inconclusive election. No new government has been formed. On Sunday, Biden sat down separately with Prime Minister Nouri al-Maliki and his chief challenger, Ayad Allawi. Both claim the right to head Iraq's new government.
