Democratic presidential candidate Bernie Sanders, responding to reports President Barack Obama called on Democrats to rally around Hillary Clinton as the likely nominee, said on Thursday it was "absurd" to suggest he drop out of the race.

Obama privately told a group of Democratic donors last Friday that Sanders was nearing the point at which his campaign against Clinton would end, and that the party must soon come together to back her, the New York Times reported.

Sanders, a Vermont senator and self-proclaimed democratic socialist, while saying he did not want to comment directly on Obama's reported remarks, pushed back on the idea that his campaign had run its course and he should throw in the towel.
