In-fighting dominates Democrat TV debate

Democratic presidential candidates Bernie Sanders and Hillary Clinton moved past the rancour over a breach of her campaign’s valuable voter data, shifting the debate into a pointed but polite discussion of national security, Americans’ heightened terrorism fears and the economy.

Clinton, the Democratic front-runner, kept much of her focus on the general election, sharply criticising Donald Trump’s plan to ban Muslims from entering the United States. She called Trump the Islamic State’s “best recruiter”.

“Mr Trump has a great capacity to use bluster and bigotry to inflame people,” said Clinton, the former secretary of state.
