Rep. Matt SalmonMatt SalmonHouse GOP talks 'minibuses,' moves toward Senate in spending fight Gloom sets in for GOP LGBT fight dooms spending bill on House floor MORE (R-Ariz.) says he remains opposed to same-sex marriage — even after his son revealed he is gay.
"I'm just not there as far as believing in my heart that we should change 2,000 years of social policy in favor of a redefinition of the family," Salmon said. "I'm not there."
Salmon's reaction contrasts with that of Sen. Rob PortmanRob PortmanSenate rivals gear up for debates Funding bill includes million for opioid crisis Senate panel approves pension rescue for coal miners MORE (R-Ohio), who said he changed his mind on same-sex marriage after his own son revealed he is gay.
"It doesn't mean that I don't have respect. It doesn't mean that I don't sympathize with some of the issues," Salmon said.
"It just means that I haven't evolved to that stage. Rob Portman apparently has."
Salmon's son, also named Matt, came out as gay several years ago.
