Spiraling violence in the Middle East and the government’s response to the flood of migrant children crossing the border are primed to dominate the Sunday talk shows.

Congressional Democrats and administration officials will look to rally support for President Obama’s $3.7 billion emergency request to address the flood of tens of thousands of unaccompanied minors across the southern border.

House Republicans have balked at the plan, with House Appropriations Committee Chairman Hal Rogers (R-Ky.) dismissing the request as “too much money” in a statement Friday.

In the Middle East, the kidnappings and murder of four teenagers, a Palestinian and three Israelis, have resulted in a fresh exchange of rocket fire across the Gaza Strip.

The U.S. has defended Israeli air strikes and military operations, calling them justified after the militant group Hamas began launching rockets into Israeli territory. More than 1,000 Palestinians are estimated to be killed or injured in the Israeli response.

On Saturday, the United Nations security council called for a de-escalation of the violence and the resumption of one-on-one negotiations between the two sides, with hopes of restarting comprehensive peace talks.
