Sen. Marco Rubio (R-FL) accused advocates of same-sex marriage of intolerance during a speech at Catholic University on Wednesday afternoon and reiterated his support for marriage between one man and one woman. While recognizing that “our history is marred by discrimination against gays and lesbians,” Rubio argued that “traditional marriage has such an extraordinary record of success at raising children” and must be perpetuated to the exclusion of same-sex unions.
