> Why would the intelligence community be involved with decision-making inside the department of justice?
Because the intelligence community hates Assange and what he represents. They spied on US lawmakers, tortured, manufactured evidence... I find it hard to believe they WOULDN'T meddle in this case.
> Obama's DoJ apparently decided not to pursue the case, why would we expect Biden's DoJ to come to a different conclusion?
Because post 2016 election the Democrats are no friends of Assange and WiliLeaks, regardless of the implications for press freedom.
