A conservative watchdog group filed a lawsuit Thursday arguing that Hillary Rodham Clinton cannot legally serve as secretary of state, even though she was sworn in last week.
The suit is based on an obscure section of the Constitution on compensation for public officials, the emoluments clause. The clause says no member of Congress can be appointed to a government post if that job's pay was increased during the lawmaker's current term.
Clinton was serving in Congress when the secretary of state's salary was raised to its current level of $191,300. So that Clinton could take the post, Congress last month lowered the salary to $186,600, the level when she began her second Senate term. A similar tactic has been used so that several other members of Congress from both parties could serve in the Cabinet.
Judicial Watch, which has pursued several suits against Clinton and other officials over the years, argues there can be no exceptions to the clause.
The group says that Hillary Clinton is "constitutionally ineligible" to be secretary of state until 2013, when her second Senate term would expire. She resigned from the Senate to take the Cabinet post.
Judicial Watch filed the suit on behalf of State Department employee David Rodearmel. It says Rodearmel would violate the oath he took as a foreign service officer in 1991 to "support and defend" and "bear true faith and allegiance" to the Constitution by working for Clinton.
A State Department spokesman declined to respond to the case.
