Syria is expected to top the agenda at this year's G-8 summit taking place in Northern Ireland.
President Obama, his wife, and two daughters arrived in Ireland on Monday.
Last week, the president announced his intention to arm Syria's rebel forces, but Rep. Mike Rogers, R-Mich., chairman of the House Intelligence Committee, said Congress needs to know what the administration has in mind before it approves any aid.
"What is the plan? Where are we going in Syria? And what do you want to accomplish?" Rogers asked on CBS's "Face the Nation" Sunday.
"It seems to me they have a great media strategy," Rogers continued. "They don't have a great Syrian strategy, and I don't believe any of our members -- and we had both Republicans and Democrats on the committee -- express concern about where they think we are today and where we think the administration wants to go."
Meanwhile, Obama plans to meet with Russian President Vladimir Putin on the sidelines of the summit to discuss the civil war in Syria.
Putin is against other countries arming Syrian rebel forces though Russia has been arming the Assad regime for decades.
