Earlier this month, Sens. John McCain (R-AZ) and Lindsey Graham (R-SC) announced their opposition to the nomination of Assistant Secretary of State Christopher Hill to be the next U.S. Ambassador to Iraq. "While Mr. Hill is a talented diplomat who has served our country for many years, his selection for this post concerns us," said the two senators in a statement. The McCain/Graham statement was the first shot fired by "a cadre of Senate Republicans" aiming to sink Hill's nomination.
