Hallie Jackson: ‘Not Illegal’ for GOP Delegates to Dump Trump at the Convention

JACKSON: "So two quick points to make there. Number one, this talk about the 'Free the Delegates' movement; you can see Trump at least publicly appears unphased, but it is still possible, it’s a so long shot, as we’ve been talking about, but it is possible, it’s not illegal for these delegates to try to make some moves in the Rules Committee, to make something happen, possibly, in Cleveland."
