The problem is that she, and other politicians of all shapes, sizes, and political affiliations, have gotten filthy, dirty rich just from being in Congress. It's not always, or even usually, just rich people getting richer. Specifically related to Pelosi and $NVDA, though, it's an issue when she or other members of congress make large transactions in a stock like this just to have the news subsequently come out that some big new advancement or trade deal involving that company has been signed. Here, allegedly, the Chinese President visits her state, she buys NVDA within the next week, then 6 days later news breaks that NVDA has developed a chip designed to get around US restrictions on trade with China. Imagine that! What fortuitous timing!
