President Barack Obama will not publicly endorse a candidate before the 2016 Democratic primaries, the White House said Sunday, according to Reuters.

White House chief of staff Denis McDonough was quoted as having told NBC's Meet the Press that Obama will be "out there" campaigning after the primary election to help support the Democratic candidate.

"We'll do exactly what has been done in the past," McDonough said.

Currently, there are three people in the running for the Democratic nomination: Obama’s former secretary of state Hillary Clinton, Vermont Senator Bernie Sanders and Maryland Governor Martin O'Malley.

Clinton continues to be the frontrunner, despite controversies surrounding her use of a private e-mail address during her entire time as secretary of state.

Reuters noted that in an op-ed piece published in the New York Times last week, Obama wrote that he would not campaign for or support any presidential candidate opposed to gun reform, even if they were from his own party.

"I will not campaign for, vote for, or support any candidate, even in my own party, who does not support common-sense gun reform," he wrote.
