What happened Tues 4/22/2025 a half hour before the bell?

I was looking at a chart of the SP500 and last Tuesday, 4/22, the index was a bit up and down until about 30 min before the end of the trading day when it shot up dramatically.

* Does anyone know what news hit the media, or what the impetus was for such a spike?
* What is your favorite source of current financial news. The sites I visit seem to feature stale news.

Thanks in advance,
