Republican National Committee chairman Reince Priebus dodged questions about whether he approves of Donald Trump’s choice of Steve Bannon to be CEO of Trump’s campaign, and said he does not know the former Breitbart executive.

Priebus, who appeared on NBC’s “Meet the Press,” said he is just getting to know Trump’s new senior aide. Bannon proudly turned Breitbart.com into “the platform for the alt-right,” a group that opposes progressive causes and values while advancing the populist approach that helped Donald Trump rise within the GOP.
