Sen. Darline Graham (R-SC) said to voters during a televised debate on Tuesday that national security is not her area of expertise [1].

The admission raises questions about the readiness of the interim senator to handle high-level foreign policy responsibilities in a critical Senate seat.

Graham, the sister of the late Sen. Lindsey Graham, faced questioning during a Republican primary debate in South Carolina [1]. The exchange occurred when the senator was pressed for her position on U.S. policy toward Taiwan and the South China Sea [1, 2]. Rather than providing a policy stance, Graham declined to answer the specific questions [1, 2].

"National security is not my thing," Graham said during the debate [1].

She further elaborated on her lack of familiarity with the subject matter as the televised event continued. "I'm not that informed on national security," she said to the audience [2].

Graham was appointed to fill the seat previously held by her brother [1]. Her comments have prompted criticism regarding her preparation for the role, as the Senate often handles sensitive intelligence, and defense authorizations. The debate was broadcast nationwide, bringing her comments to a broad audience of voters and political analysts [1].

"I’m not that informed on national security," Graham said when asked about Taiwan and the South China Sea [3].

"National security is not my thing,"

This admission is significant because the U.S. Senate plays a primary role in treaty ratification and the confirmation of defense officials. For a senator to publicly disclaim expertise in national security—particularly regarding volatile regions like the South China Sea—may create a perceived vacuum in leadership for South Carolina's representation on the global stage.
