New Trump campaign manager to push candidate to focus on policy

"Keep giving these policy speeches, because I tell you ... there's absolutely zero evidence that the voters want this election to be about this content-free cacophony with no substance and no issues," Kellyanne Conway said in an interview with Fox News.

Conway was named to the position on Wednesday by the Trump campaign in a shake-up that also appointed the head of conservative website Breitbart News to the new position of campaign CEO.
