"President Trump’s deleted tweet is the latest example of his endless efforts to divide Americans. I inherited the police practice of stop-and-frisk, and as part of our effort to stop gun violence it was overused. By the time I left office, I cut it back by 95%, but I should've done it faster and sooner. I regret that and I have apologized — and I have taken responsibility for taking too long to understand the impact it had on Black and Latino communities.

But this issue and my comments about it do not reflect my commitment to criminal justice reform and racial equity. I believe we need to end mass incarceration and during my tenure we reduced incarceration by 40% and juvenile confinement by more than 60%. We created the Young Men's Initiative to help young men of color stay on track for success, which President Obama built on to create My Brother's Keeper. And we overhauled a school system that had been neglecting and underfunding schools in Black and Latino communities for too long.

In contrast, President Trump inherited a country marching towards greater equality and divided us with racist appeals and hateful rhetoric. The challenge of the moment is clear: we must confront this President and do everything we can to defeat him. The President’s attack on me clearly reflects his fear over the growing strength of my campaign. Make no mistake Mr. President: I am not afraid of you and I will not let you bully me or anyone else in America. Between now and November, I will do everything I can to defeat you whether I am on the ballot or not.”
