Russian intelligence agent linked to Trump campaign among Kremlin figures sanctioned by Biden

A Russian intelligence agent accused of attempting to undermine US election integrity and sow disinformation was among Kremlin-linked figures targeted in Russian sanctions announced on Thursday.

Federal authorities alleged that Konstantin Kilimnik "provided the Russian Intelligence Services with sensitive information on polling and campaign strategy" for former president Donald Trump in 2016.

The allegations connect to findings from Robert Mueller's investigation and congressional investigations that assessed Mr Kilimnik was fed information by former Trump campaign manager Paul Manafort.
