Republican presidential hopeful Marco Rubio is promoting his Christian faith as he campaigns across Iowa.
The Florida senator, a Catholic, says faith "is the single greatest influence" in his life. He opened up about religion when confronted by an atheist during a town hall-style meeting Monday in Waverly, Iowa.
Rubio told the atheist that "no one's going to force you to believe in God." Then he charged, "But no one's going to force me to stop talking about God."
Rubio is trying to break out of the crowded Republican field just two weeks before Iowa's leadoff caucuses. Christian conservative voters typically play outsized influence in the opening contest.
Rubio also renewed his opposition to abortion and promised to strip funding from Planned Parenthood.
