Secretary of State John Kerry returns to Capitol Hill this coming week for a tough grilling on Russia's intervention in Syria and what the Obama administration is doing about it.

The Senate Foreign Relations Committee is scheduled to hear from Kerry in a closed session Oct. 27 about the administration's response in the Syrian conflict. The briefing comes amid growing Republican anger over the administration's failure to prevent Russian airstrikes against US-backed rebels and follows a subpoena threat from Chairman Bob Corker, R-Tenn.

Corker's committee is also set to hear Oct. 28 from the State Department's top Middle East official, Assistant Secretary Anne Patterson, and President Barack Obama's envoy for the global coalition against the Islamic State, retired Gen. John Allen, about the "US role and strategy in the Middle East." Allen will be stepping down Nov. 12 and will be succeeded by his deputy, Brett McGurk.
