Officer Brian Sicknick's death is described in the Wikipedia piece linked below. It's Wiki, but I don't see any leftist bias in it. Sicknick died of two strokes. He was not killed by the protesters.

Regarding police deaths, I assume that factcheck.org is a leftist site, but at least they tried to make the numbers add up. Most of the police deaths were suicides, some of which occurred months after the protest.

So is the WH lying?
Yes. The protesters may have put the officers through a stressful day, but that's what they signed up for when they became police officers. The protesters killed NO police. NONE!
