Presidential adviser and son-in-law Jared Kushner is reportedly the latest target in the ever-widening investigation into Russian meddling in the 2016 election.

Special counsel Robert Mueller, who is leading the investigation, is reportedly looking into the real estate scion’s finances and business dealings after it was revealed that Kushner met with Sergey Gorkov, the head of the state-owned Russian development bank Vnesheconombank, in December, the Washington Post reported.
