Republican Representative Nancy Mace has publicly questioned whether Darline Graham, President Donald Trump’s preferred candidate to succeed her late brother, Senator Lindsey Graham, is eligible to appear on South Carolina’s Republican primary ballot. The intervention marks a break with Trump’s endorsement and could intensify scrutiny of the state’s Senate contest.

Mace said Graham had “no record” and expressed uncertainty about her qualifications, though the supplied article excerpt does not set out the specific legal basis for the challenge. Graham is seeking a full Senate term in South Carolina, where the dispute centres on her eligibility for the Republican primary ballot.
