“It is time for us as Democrats to be as tough as they are, to be as dedicated as they are, to be as committed as they are,” Holder said. “Michelle always says, Michelle Obama, I love her. She and my wife are really tight. Which always scares me and Barack. Michelle always says,

Kamala Harris on the Late Show with Stephen Colbert said this about BLM protests in June 2020:
They're not going to stop before Election Day in November, and they're not going to stop after Election Day," Harris continued. "Everyone should take note of that on both levels, that they're not going to let up and they should not and we should not."
"Almost every one of those marches has been about one fundamental ideal in our country, which is equal justice under law," she said. "And
fighting to make sure that we have a government and a country that, at least every few steps, gets closer to achieving that ideal." While the United States has not yet reached equality for all, Harris said that protests "are the catalyst to getting there."

This was said in June, but Kamala did not draw a distinction or explicity condemn violence until August 27.
"Harris condemned violent protests on Aug. 27 after multiple nights of looting and two violent deaths."

What took her so long to call out violence? Poll numbers showing majority of Americans were against violent protests? Telling them to "fight", as they did, can be interpreted as encouraging or even inciting.
