The goal is unity, but Republicans still seem far from it when it comes to support of presumptive nominee Donald Trump.

FOX's Gurnal Scott reports:

New York congressman Chris Collins was one of the first to supports Trump in part because he comes from the private sector:

(Collins) "Someone who has been a Chief Executive. We've seen what happened with a legislator Barack Obama, the imperial presidency, the last seven and a half years."

But fellow New York representative Peter King says some of Trump's foreign policy positions concern him for example:

(King) "If he does want to get into a trade war with China he has to explain how that coincides with wanting to use China against North Korea."

Both appeared on CBS' Face the Nation. House Speaker Paul Ryan also on the fence, has set no time table for a Trump endorsement.
