Obama to endorse Biden for president

(CNN) — Former President Barack Obama will endorse Joe Biden on Tuesday, a source familiar with the plans tells CNN.

Obama will make the endorsement of his former vice president in a video message, offering why he believes Biden is the candidate needed at this moment of crisis in America, a person close to the former president says.

The endorsement reunites the former running mates and positions Obama, whose endorsement of Biden was seen as a forgone conclusion once Vermont Sen. Bernie Sanders dropped out of the race last week, to be one of Biden’s most powerful surrogates in the race against President Donald Trump.

It also marks the public re-emergence of Obama into the political arena. The former president kept a low public profile throughout much of the Democratic nomination fight, but he was active behind the scenes.

Obama in November said he had spoken to all of the candidates during the campaign, often giving them advice both before they announced their bid and after they dropped out. Advisers to the former president said his advice was often the same: Consider why you believe you should be president, what impact it will have on your family and whether you can actually win.
