Republican presidential candidate Ted Cruz on Thursday targeted the Supreme Court's June finding that gay and lesbian couples have a constitutional right to marry, saying that it “will not stand.”

Speaking at the Carolina Values Summit at Winthrop University, Cruz called the decision “lawless,” and took aim at his GOP rivals.

Without naming Donald Trump and Florida Senator Marco Rubio by name but as his top two challengers, Cruz suggested that their opposition to marriage equality was weak.

Both candidates have said that they would like to see the high court's ruling overturned but that they would abide by the “law of the land.”

“Those are the talking points of Barack Obama,” Cruz told the crowd.

Cruz and Rubio have pledged to push for passage of the First Amendment Defense Act (FADA), which seeks to bar federal “discriminatory action” against people who oppose gay couples marrying based on a “religious belief or moral conviction.”
