He should sue the Enquirer.
Make them come up with the evidence or admit it is nothing but a stupid rumor.
Something about Cruz I don’t like, regardless of how much I like his position on some issues. Obviously, support the winner of the primaries in the general, but there’s something Elmer Gantry of him, like a higher (much) IQ Huckabee.
The Enquirer specifically reported that it is a rumor. That is how the Enquirer avoids libel suits from public figures. Cruz could attempt to sue for defamation, but oral arguments would not likely be heard until summer 2018.
