President Obama To Endorse Hillary Clinton

From the New York Times:

President Obama, after months of sitting on the sidelines of the rancorous contest to succeed him, is now ready to aggressively campaign for Hillary Clinton, starting with a formal endorsement of her candidacy as early as this week. The White House is in active conversations with Mrs. Clinton’s campaign about how and where the president would be useful to her, according to senior aides to Mr. Obama.

Advisers say that the president, who sees a Democratic successor as critical to his legacy, is impatient to begin campaigning. They say he is taking nothing for granted. It has been decades since a second-term president enjoyed the popularity to make him a potent force on the campaign trail and also an invitation from the candidate running to succeed him to be a major presence there.
