( CNN ) -- Hillary Clinton was confronted by immigration reform activists in Iowa over the weekend . The activists accused President Obama of breaking promises to immigrants and wanted to know what Clinton would do about the issue . She told them to `` elect more Democrats . '' The former secretary of state and likely future presidential candidate was signing autographs and T-shirts and participating in selfies in Iowa on Sunday when a DREAMer tried to turn the conversation to immigration and deportations . Monica Reyes announced herself as a DREAMer , an undocumented immigrant brought to the U.S. by parents . Clinton , wearing black sunglasses , responded , `` Yay . '' `` I was wondering what you feel about Obama 's delay on immigration , '' Reyes asked Clinton in an in an exchange caught on video by immigration reform activists . While Clinton continued down the line of people behind metal barriers , she responded , `` I think we have to keep working -- ca n't stop ever working . '' President Barack Obama recently announced that he was postponing his announcement to address broken immigration policy until after the elections . The decision infuriated immigration advocates , who were already disappointed in the record number of deportations during Obama 's tenure . Cesar Vargas , a member of the DRM Coalition standing next to Reyes , pointedly followed up . `` The President has broken his promise to the Latino community , and we wanted to know if you stand by the President 's delay on immigration , '' he said . Clinton kept moving but said , `` You know , I think we have to elect more Democrats . '' Hillary Clinton 's return to Iowa : a fresh start or deja vu ? This was the first time Clinton had been to Iowa as a politician since she lost the caucuses there in 2008 to then-Sen. Barack Obama . At Democratic Sen. Tom Harkin 's annual steak fry in Indianola on Monday , her speech , filled with foreshadowing innuendos , added to the speculation that Clinton is seriously plotting a second presidential run . Vargas and fellow DREAMers also confronted Vermont Sen. Bernie Sanders , a self-described socialist who is toying with a presidential run , in Iowa over the weekend . On Twitter , Vargas wrote that Sanders hit a `` home run '' while Clinton struck out . But the activists ' attendance at the Clinton and Sanders events signals that the immigrant community and immigration advocates are going to put political pressure on candidates contemplating a presidential run . `` The message we want to make clear to them is they should not take our community for granted , '' Cristina Jimenez , co-founder of United We Dream , told CNN . Latinos , who are not the only community affected by deportations but recently has been the largest , tend to vote for Democrats . They backed Obama overwhelmingly -- by more than 70 % -- in the 2008 and 2012 elections . `` We ask Republicans the question 'why do they want to deport us , ' and we 're going to do the same thing with Democrats , '' Jimenez told CNN . `` Both parties have really failed our community . '' DREAMers interrupted one of Sen. Marco Rubio 's events in South Carolina , also a key presidential nominating state , last month . And earlier in August , Kentucky Sen. Rand Paul abruptly left a lunch table in Iowa when Vargas and fellow DREAMers confronted colleague and immigration hard-liner Rep. Steve King .
