Maybe corrupt is too harsh but I don't think so. I don't trust McConnell because his record for several years has been less than stellar. His votes on multiple key issues has been with the Dems and against the interests of the country. As leader of the senate, a position of considerable power, he did much of the same.
In addition, McConnell's physical and mental abilities have declined considerably in the last few years to the point that he is incapable of doing his job now. We learned recently that he had a major medical episode, possibly a heart attack, and is in dire health. There are some reports that he is near death or even already dead. He and his staff have placed their selfish interests above that of the nation, a very egregious and dangerous prospect. The four nightmare of Pres Biden illustrates that point clearly.
McConnell should have retired long ago. He is another example of a geriatric politician who has remained in power far too long. In my mind, that's further evidence of corruption.
“Incline my heart to your testimonies, and not to selfish gain!”
