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.

President’s speech, declassification of documents and heightened claims of noncitizen voting have experts concerned

A series of moves by Donald Trump’s administration to sow doubt in the integrity of US elections has intensified concern among voting experts – and sparked hope among election deniers – that it could declare a national emergency.

The White House and US federal agencies have released a string of documents this summer – including disputed analyses of alleged voting by noncitzens and historical intelligence memos – stoking expectations that the US president could move to exert greater control over November’s US midterm elections.
