Kamala Harris is the president-in-waiting. Here's how the VP is balancing building her own brand against serving as a loyal soldier on Team Biden. https://t.co/2HTKlpmEd9 by @rbravender & @TinaSfon ($) @businessinsider

Kamala Harris is the president-in-waiting.

It's the awkward reality that has always come with being second-in-command. The vice president's principal job function is to be ready to step in if she's needed.

At the same time, Harris can't appear over-eager to get the top job, and Democrats bristle at questions about whether she's interested in a future White House run or whether Biden — the oldest president in US history at age 78 — intends to try for a second term in 2024.

So — just like (the male) veeps who came before her — Harris & her team must walk the fine line of protecting her image & building a brand while also portraying her as a loyal Biden soldier & dismissing any speculation that she's eyeing another presidential run of her own.

Harris was "an icon before she even set foot in the White House," said Joel Payne, a Democratic strategist who worked on Hillary Clinton's 16 campaign. "I think she's a bridge to the next generation of Democrats" and a bridge to progressives, women, and people of color, he added.

NEW: After the violent and mostly White pro-Trump mob attacked the Capitol last week, Black & brown people had to clean up the mess. Several told @Politicsinsider they were well aware of the racial dynamics. By @elvina_nawaguna & @KaylaEpstein ($)

The Trump supporters who broke into the Capitol left behind shards of broken glass and ripped-apart furniture, blood, empty bottles, and even feces smeared on the walls.

The custodial staff cleaned up in places where people were bludgeoned & in one instance fatally shot, & where dozens of Capitol Police officers were wounded. "It felt bad. It's degrading," said a custodial employee in his 30s, who works for the Architect of the Capitol.

Several Capitol janitorial and labor employees — all of whom were Black or Latino — told Insider they no longer feel safe at their workplace, which is supposed to be one of the most secure in the country.

They recounted the hurt of cleaning up after white nationalists who could have threatened their lives, and they feared what's yet to come in the days leading to and on Inauguration Day.
