WASHINGTON (AP) — Republicans and Democrats say the Obama administration is not placing a priority on congressional authorization of the U.S. war against Islamic State extremists.

Lawmakers say the White House has yet to outline what it wants from Congress or to send top officials to testify on Capitol Hill.

Senators will get a chance to ask questions of a top Obama foreign policy adviser today when Tony Blinken, the president's choice to become the State Department's No. 2 official, testifies at a nomination hearing.
