Exasperation and dysfunction: Inside Kamala Harris' frustrating start as vice president

Worn out by what they see as entrenched dysfunction and lack of focus, key West Wing aides have largely thrown up their hands at Vice President Kamala Harris and her staff -- deciding there simply isn't time to deal with them right now, especially at a moment when President Joe Biden faces quickly multiplying legislative and political concerns.

The exasperation runs both ways. Interviews with nearly three dozen former and current Harris aides, administration officials, Democratic operatives, donors and outside advisers -- who spoke extensively to CNN -- reveal a complex reality inside the White House. Many in the vice president's circle fume that she's not being adequately prepared or positioned, and instead is being sidelined. The vice president herself has told several confidants she feels constrained in what she's able to do politically. And those around her remain wary of even hinting at future political ambitions, with Biden's team highly attuned to signs of disloyalty, particularly from the vice president.

She's a heartbeat away from the presidency now. She could be just a year away from launching a presidential campaign of her own, given doubts throughout the political world that Biden will actually go through with a reelection bid in 2024, something he's pledged to do publicly and privately. Or she'll be a critical validator in three years for a President trying to get the country to reelect him to serve until he's 86.
