WASHINGTON  — Leaders of the House and Senate intelligence committees on Sunday prodded President Barack Obama to take decisive action against what they say are growing threats from Islamic State militants on U.S. soil.

The lawmakers, one Republican and one Democratic, offered bipartisan pressure on the White House to turn back the hazard of Islamist fighters who have taken control of vast swaths of Syria and Iraq. Those militants now are looking toward the United States or Western Europe for its next targets, lawmakers said.

Without offering specifics on any threats or suggestions how to confront them, the lawmakers said Obama soon needs to develop a comprehensive strategy to crush the fighters.

“His foreign policy is in absolute free-fall,” said Rep. Mike Rogers, a Michigan Republican who heads the House Intelligence Committee.

In another TV interview, Sen. Dianne Feinstein, the California Democrat who leads the Senate intelligence panel, said Obama is perhaps “too cautious” in his approach to combatting the Islamic State group.
