Tim Scott defends Darline Graham’s ‘national security is not my thing’ comment

Republican senator tries to assuage concerns but does not offer details of Graham's national security experience

Tim Scott defended fellow US South Carolina Republican senator Darline Graham's knowledge of national security issues ahead of their state's runoff election on Tuesday.

Graham, who was appointed to fill the Senate seat held by her brother Lindsey Graham after his sudden death in July, is in a Republican primary runoff against South Carolina congressman Ralph Norman. During a debate between the two on Tuesday night, Graham struggled to answer a question about US national security interests in Taiwan and the South China Sea.
