BOSTON (AP) — Two Massachusetts students say they staged a marriage proposal at a Ted Cruz rally as a demonstration against the Republican presidential hopeful's stance on gay marriage.

Emerson College sophomores Arden Jurskis and Kenzy Peach tell The Boston Globe ( the fake engagement at Sunday's rally in Iowa was "spur of the moment" and a "demonstration of values and activism."

Cruz believes marriage should be between a man and a woman. Jurskis is a man. Peach is a woman.

But Peach says same-sex marriage is more ethical than the marriage of two college sophomores.

A photo that's been widely shared online shows Jurskis and Peach embracing moments after Jurskis pretended to propose, while Cruz looks on, his hands raised in mid-clap.

The students are on a school trip at the caucuses.
