Too many politicians make millions while in office because their policies are biased toward benefitting companies they’re invested in. Nancy Pelosi is notoriously one of the “best investors” in the country almost as if she has insider information and the power to sway things in her favor.
The same goes for bribes and endorsments. Its a clear sign of corruption when a politician makes a fortune while in office and it needs to be investigated. They are clearly not intending to serve the people, they are there to take advantage of their position for financial gain.
