Did Joe Biden get angry over the acquittal of Kyle Rittenhouse? And did he refuse to take back his baseless assertion that Kyle Rittenhouse is a "white supremacist"?

I'm seeing headlines to that effect — for example, "Kyle Rittenhouse: Biden angry after teen cleared of shootings" (BBC). Biden spent part of yesterday morning under sedation, getting a colonoscopy, but he was back in the world of the conscious by the time the verdict came out, able to hear the news and fly into a seething rage or whatever happened that got reported as anger.

First, let's look at the video. Video was important in the Kyle Rittenhouse trial, and it's important now as we judge the emotional state of our President:

He's asked for a reaction to the verdict, which he says he just heard, and his first words were exactly what a calm, rational person would say if he didn't watch the trial: "I didn't watch the trial." The reporter loads in a challenge: "Do you stand by your past comment" accusing Kyle Rittenhouse of "white supremacy"?

Biden is cautious: "Well, look, I stand by what the jury concluded. The jury system works, and we have to abide by it." That is absolutely not anger. He's not losing his cool in the slightest, and he simply ignores the problem of his ignorant remark about white supremacy. And that's the end of it. Immediately, there's another question on another topic (his health). 

Second, there's a "Statement by President Biden" at the White House website. Here's the whole thing, and I've put the anger material in boldface:

While the verdict in Kenosha will leave many Americans feeling angry and concerned, myself included, we must acknowledge that the jury has spoken. I ran on a promise to bring Americans together, because I believe that what unites us is far greater than what divides us. I know that we’re not going to heal our country’s wounds overnight, but I remain steadfast in my commitment to do everything in my power to ensure that every American is treated equally, with fairness and dignity, under the law.

I urge everyone to express their views peacefully, consistent with the rule of law. Violence and destruction of property have no place in our democracy. The White House and Federal authorities have been in contact with Governor Evers’s office to prepare for any outcome in this case, and I have spoken with the Governor this afternoon and offered support and any assistance needed to ensure public safety.

I don't know who wrote that, and I very much doubt that Biden had much involvement, but the tone is about calmness. Anger is only there to be acknowledged. It's a first step toward gaining composure: I know you're angry but....  

Yes, the statement includes Biden in the feeling of anger — "myself included" — but that doesn't make me feel as though Biden is actually angry.

The verdict didn't make me angry. I watched the trial from the point where Rittenhouse took the stand, and it seems obvious to me that, given the burden of proof, acquittal was the right result. I'm sure Biden knows that too, and so there's nothing about the verdict that should make any knowledgable person angry. 

I am angry about some things other than the verdict. I'm angry that Governor Evers didn't take steps to end the violence before it devolved into the chaos that Rittenhouse entered. I'm angry that the media did such a terrible job of reporting on the Jacob Blake incident that inflamed people and led to the violence. And I'm angry at Joe Biden for contributing to the inflammation back when he called Rittenhouse a white supremacist.

Some anger is justified, and I don't know exactly what the White House statement is designating as the cause of Biden's anger. Frankly, I think it's nothing but rhetoric, intended to pull in angry citizens and make them want to go along with Biden's appeal to keep the peace. If I were one of those angry citizens — if I believed that the entire Kenosha story reeked of systemic racism — I would not for one second believe that Biden authentically shares my anger.
