Conservative radio host Glenn Beck called on the thousands assembled for the Rally to Stop the Iran Deal to fight for the lives of all.

Beck joined Republican presidential hopefuls Donald Trump, Ted Cruz and Rand Paul in speaking out against the nuclear deal that would allow Iran to take in billions of dollars in previously frozen assets while still being able to keep out international inspectors.

"Let us begin here and now," Beck said, "to fight for something. Fight for life, fight for decency, fight for the women who are devalued, the homosexuals who just want to live, fight for the children who are crucified and raped up to ten times a day. Fight for life, fight for light because light will conquer the darkness."

Beck's appearance at the event was notable given his opposition to Trump. Beck has used his radio and online platform, The Blaze, to promote candidates such as Cruz and Paul.
