Senators warn Abadi that ISIS could return to Iraq

Conflict between U.S. partners in Iraq could lead to a resurgence of the Islamic State terrorist group, a bipartisan group of senators has warned.

Eight lawmakers are urging Iraqi Prime Minister Haider al-Abadi to strike an agreement that would end a crisis between the central government and the Kurds, who voted to secede from Iraq and form their own state. The tensions put the United States in a difficult position because American officials are working to strengthen the Iraqi government, while the Kurds played a critical role in expelling ISIS from the country.
