Senate Majority Leader Mitch McConnell predicted Tuesday that although Donald Trump has become the presumptive Republican presidential nominee, he will not change the GOP as an organization.

In an interview with radio host Hugh Hewitt, McConnell said Trump will be much like other GOP nominees and presidents who weren’t in line with the orthodox GOP, such as former President Dwight Eisenhower. However, McConnell said he feels “comfortable” casting his ballot for him, and cited the Supreme Court has a main reason.
