Kushner is also weighing in on domestic policy. He joined other Trump advisers Monday night for a meeting with House Speaker Paul Ryan, R-Wis., on tax reform. He championed the pick of his friend Gary Cohn, the president of Goldman Sachs, for a top White House economic post, and Cohn's influence within Trump's team is said to be growing. He's been a conduit between Trump's team and the private sector, a role transition officials said would continue in the White House.
