WASHINGTON (Reuters) - Former CIA Director John Brennan said on Tuesday that he does not know whether President Donald Trump's 2016 presidential campaign colluded with Russia but that he saw "information and intelligence that was worthy of investigation."

In addition, the country's top intelligence official, Dan Coats, declined to say, as reported by the Washington Post, whether Trump had asked him to publicly deny that any evidence exists on collusion between his campaign and Moscow.
