Top Republicans still refusing to endorse Donald Trump

Donald Trump was officially named the Republican presidential nominee during July's Republican National Convention--but some party leaders are still not on board with his candidacy.
During the week long gathering in Cleveland, while names the likes of Chris Christie and Mitch McConnell tossed their political weight behind the billionaire businessman, a number of prominent GOPers not only skipped the convention but have refused to endorse the party's ticket.
Perhaps the most high-profile political snub of the 2016 election cycle came at the hands of Texas Senator Ted Cruz, who was promptly booed after failing to endorse Trump during his prime-time address at the RNC.
