Former President Barack Obama and Vice President Kamala Harris have been in close touch since she announced her presidential candidacy Sunday, having multiple conversations this week as she kicks off her campaign, according to four people familiar with their discussions.

Obama privately has fully supported Harris’ candidacy and plans to endorse her soon, these people said.
"He has been in regular contact with her and thinks she's been off to a great start," one of them said.

Obama is one of the only high-profile Democrats in the country who has yet to endorse Harris. While other party leaders have stepped forward to publicly back her, he has so far kept his support private.
