Obama harassed by heckler during Caucus as he promises angry Hispanics he 'will not to give up' on immigration reform

President Barack Obama sought to rally frustrated Latinos on Thursday with a firm promise to keep fighting for immigration reform and a renewed pledge to take executive action this year to reduce deportations of undocumented immigrants.

After enraging many Hispanic voters last month by delaying a change in immigration policies until after the November midterm elections, Obama has faced widespread condemnation from a voting bloc that helped him win the presidency in 2008 and 2012.

Latinos remain critical to Democrats' hopes of holding onto the White House, not to mention Obama's legacy, so the president said he would use the coming weeks to gin up support among the U.S. public for another shot at reform.

Speaking at an annual gala held by Hispanic lawmakers, Obama said he shared the group's frustration but needed its support to make any reform last beyond his presidency, which concludes in a little more than two years.
