Bannon's right-leaning ideologies clashed with Kushner's more moderate approach to things.
Bannon has made it clear that he intends to settle old scores within the White House and the Republican establishment.
Did US president Donald Trump's daughter Ivanka, who is married to Jewish-American millionaire Jared Kushner, support the firing of Steve Bannon? Kushner represented the "globalist" influence on the Trump administration's policies, which typically ran athwart the isolationist white nationalist stance of Bannon and his acolytes in the White House.
The ousted White House chief strategist wants to implicate President Trump's son-in-law and senior adviser in the decision to fire then-FBI Director James Comey, Vanity Fair reports.
Bannon's ouster was no less than a move "to save the (Trump) presidency", a source close to Ivanka claimed.
Bannon, who has returned to his Executive Chairman position at the news organization, Breitbart, certainly seems to have the power to launch a war against former foes within the West Wing. It will be interesting to watch and see if Kushner fights back in any way, via possible leaks to the press about Bannon.
