New Jersey Governor Chris Christie, who helped put Jared Kushner’s father in prison, showed no mercy toward the senior White House adviser on Tuesday, encouraging Russia probe investigators to closely examine any hand he may have had in potential wrongdoings by the Trump campaign.

President Donald Trump’s son-in-law “deserves the scrutiny, you know why?” Christie said on MSNBC’s “Because he was involved in the transition and involved in meetings that call into question his role.

“Well then if he’s innocent of that, then that will come out as (special counsel Robert) Mueller examines all the facts. And if he’s not, that will come out too,” Christie continued.

Kushner was the “very senior member” of the president’s transition team who ordered former national security adviser Michael Flynn to contact Russian officials to try to stop a United Nations resolution condemning Israeli settlement activity before Trump was inaugurated, various news outlets reported earlier this month.
