Clinton Says Trump Must Not Have Nuclear Codes

US presidential hopeful Hillary Clinton has warned that electing Donald Trump would be a “historic mistake”.

Speaking in San Diego, California, the Democratic front-runner launched her most blistering attack yet on her likely Republican rival in November’s White House election.

The former Secretary of State assailed Mr Trump’s foreign policy pronouncements, saying: “He is temperamentally unfit to hold an office that requires knowledge, stability and immense responsibility.

“This is not someone who should ever have the nuclear codes.”
