REUTERS/Mike Segar In her first week on the presidential campaign trail, former Secretary of State Hillary Clinton appears to be trying to modify her positions on two prominent issues.

On Wednesday and Thursday, Clinton's campaign seemed to disavow her more moderate positions on same-sex marriage and immigration policies, though a Clinton aide later rejected the notion that she flip-flopped on both issues.

Clinton's 2008 White House bid stumbled when she praised New York's push to provide driver's licenses to immigrants who entered the country illegally — while maintaining that she opposed them. She later said in a statement, "As president, I will not support driver's licenses for undocumented people."

But in a Huffington Post story published Thursday, a Clinton representative indicated the presidential candidate now holds the opposite opinion.

"Hillary supports state policies to provide driver's licenses to undocumented immigrants," her campaign said.

However, a Clinton aide told Business Insider that context surrounding the driver's license issue had fundamentally changed since her previous campaign. The aide noted that President Barack Obama's recent executive action shielded millions of immigrants from deportation, and "support for things like drivers licenses naturally flows from that."

"The immigration landscape of 2015 is far different from the immigration landscape of 2007, so of course the policy responses are different. In 2007, we didn't have an executive action that would focus our resources on deporting felons, not families, allowing millions of undocumented immigrants to remain in the United States," the aide said. "In the last eight years, states have increasingly been moving in this direction with positive results. Hillary supports those state efforts. As she said in 2007, she believes the long-term solution is comprehensive immigration reform, but given Republican obstruction, we can no longer wait for that."

The day before, Clinton's campaign also appeared to shift her position on whether same-sex marriages should be legalized at the state level or mandated by the Supreme Court. As recently as 2014, Clinton had suggested same-sex marriage legalization should occur on a state-by-state basis.

"Marriage had always been a matter left to the states. And in many of the conversations that I and my colleagues and supporters had, I fully endorse the efforts by activists who work state-by-state," Clinton told NPR's Terry Gross, according to a transcript.

After BuzzFeed wrote a story about how Clinton had not weighed in on the coming Supreme Court case on same-sex marriages, however, her campaign told the outlet that Clinton believed there was a constitutional right to such unions and hoped the court would require all states to allow them.

"Hillary Clinton supports marriage equality and hopes the Supreme Court will come down on the side of same-sex couples being guaranteed that constitutional right," a Clinton spokeswoman told BuzzFeed.

The same Clinton aide told Business Insider that it would be incorrect to interpret Clinton as having changed her position on this issue as well. The person said when Clinton announced her support for same-sex marriages in 2013, she was doing so unequivocally.

"Hillary made it very clear that she supports marriage equality as both a matter of policy and law," the aide said. "This is what she meant. A same-sex couple has the same right to get married as an opposite-sex couple. Supporting past state-based efforts does not negate that support."
