AOC suggests it's a waste of time to investigate Joe Biden for exchanging influence for money

Democrat Alexandria Ocasio-Cortez appears to be worked up in this latest political video.AOC suggests it's a waste of time to investigate Joe Biden for exchanging influence for money. However, is it only a waste of time because Joe Biden is a Democrat? It seems like investigating any politician who is accused of overstepping their power for any reason other than taking care of America should be investigated, especially if there's potential corruption going on. And if you know anything about politics, then you know corruption is a big part of it. Investigate them all and let the people decide.
