Special counsel Robert Mueller is looking into a series of late-night telephone calls from then-candidate Donald Trump to his confidant Roger Stone during the 2016 presidential campaign, the Washington Post is reporting.

According to the Post:

Caller ID labeled them “unknown,” but Roger Stone said he knew to pick up quickly during those harried months of the 2016 presidential campaign. There would be a good chance that the voice on the other end of the line would belong to his decades-long friend — the restless, insomniac candidate Donald Trump — dialing from a blocked phone number.

The Post reported that Mueller has a “very keen interest” in those late-night talks.

Mueller’s high degree of interest in Trump’s relationship with Stone was set forth in a draft court document this week in which prosecutors drew a direct line between the two men. - PoliticusUSA
