I like that Kushner is a Democrat  and has moderate to liberal views that moderate and shape some of Trump's positions. I think he is responsible for Trump's new found respect for Muslims and his willingness to sell them state of the art weapons and fight on their side in Yemen, Somalia, Iraq, Syria, and Afghanistan. He is said to have pursuaded Trump to increase our admission of refugees from 800 to 1,500 to cut into the deficit of tens of thousands as just reported. Kushner was a supporter of Trump's itinerary instead of Steve Bannon (according to far right websites). According far right websites Kushner was also responsible for the missile attack in Syria which was opposed by Bannon. Kushner is part of a group that includes Sec. State Tillerson, Sec. Defense Mattis, national security advisor McMaster, and Ivanka which is trying to get Trump to remain part of the Paris accord on Climate Change.
