(CNN) - Sen. Ted Cruz appeared to distance himself again from fellow GOP Sen. Rand Paul, this time over social values.
The first-term Republican senator from Texas, who was in Iowa Tuesday, was asked by the Des Moines Register about Paul's recent comments that Republicans should "agree to disagree" about social issues.

Cruz seemed to disagree, saying, "I think that we should continue to defend our shared values."
"There are some who say the Republican party should no longer stand for life. I don't agree with that," he also said. "There are some who say the Republican party should no longer stand for traditional marriage. I don't agree with them, either."
Paul, who's considered more libertarian-leaning than Cruz, said in an interview that Republicans will have to draw an internal ceasefire over social issues in order to expand.
"The Republican Party is not going to give up on having quite a few people who do believe in traditional marriage," he told the website Vocativ.com. "But the Republican Party also has to find a place for young people and others who don't want to be festooned by those issues."
The two senators normally line up on a range of issues. They were both elected with strong tea party support and have vowed to shake things up in Washington.
But as Cruz and Paul consider presidential bids for 2016 and fight for the conservative base, the two have made comments that further distinguish themselves in recent weeks, particularly over foreign policy and ways to broaden the Republican Party.
