Maine Sen. Susan Collins, the top Republican on the Homeland Security and Government Affairs Committee, backed up her chairman, Lieberman, and dinged McCain, a member of the panel, for missing Wednesday’s nearly two-hour briefing in the Capitol.

Both Armed Services Committee Chairman Carl Levin, “who was there at briefing, and Sen. McCain, who was not, are members of our committee, and I know they would play very important roles,” Collins told POLITICO after the briefing.

“I do not see the benefit of creating a brand new committee when we already have the Senate’s chief oversight committee, plus the Intelligence Committee, examining this very important matter.”
