Jared Kushner, more than anyone else, is the man at the intersection of the various threads of the Trump/Russia scandal.
He attended the Trump Tower meeting with Russian lawyer Natalia Veselnitskaya that was set up under the understanding that it was part of a Russian government effort to assist the Trump campaign. He met with Russian Ambassador Sergey Kislyak during the transition and discussed possible ways to set up a line of communication between himself and Moscow that would be impenetrable by US intelligence agencies. He met with the head of a Russian state-owned bank, to discuss either American sanctions on Russian financial institutions or Russian investment in Kushner-owned properties or both. And he oversaw the Trump campaign data operation, which, according to McClatchy, is being probed for possible links to Russia's propaganda efforts.
Last but by no means least, multiple press accounts suggest that Kushner was the senior Trump official most firmly in favor of the plan to fire the FBI director in a failed effort to shut down the Russia investigation.
Yet Kushner has thus far largely escaped extensive scrutiny. Unlike other members of the Trump administration, he essentially never speaks on the record or appears on television. And unlike most of the other players in the Trump-Russia drama, there's no talk of calling him to testify in the open before Congress. Kushner has the best legal team of anyone in Trumpworld, led by former Clinton administration Deputy Attorney General Jamie Gorelick, and he appears to run a savvy PR strategy based on deploying dishy anonymous leaks to garner good coverage for himself.
Consequently, the person who should be at the center of the story is often left out of the narrative.
