Donald Trump said Wednesday that he believes the hack of emails of officials of the Democratic National Committee was backed by Russia.

At a press conference in New York, Fox News reporter John Roberts asked Trump if he agreed with the assessment of intelligence officials who briefed the president-elect last Friday that Russia was behind the hack, which resulted in the exposure of emails among DNC and Hillary Clinton campaign officials last year. The intelligence community also believes there was a failed attempt to hack the Republican National Committee as well.
