So I read the article and I have a few issues with it:
1. The claim that " What should have been a serious bipartisan inquiry into an array of constitutional violations by the Trump administration has been turned into a prime-time campaign commercial for a Democratic Party running on fumes. " is completely disingenuous when it fails to mention that Pelosi tried to do just that but the GOP derailed it.
2. It is a classic case of whataboutism. Lobbying and special interests are a massive issue, I will not argue with that, but the lack of action by conress on that front does not invalidate a congressional hearing on what was a violent attempt to interfere with an orderly transition of power.
3. There has definitely been new info in these hearings. Witnesses, under oath, have confirmed that Trump and his team knew he had lost. The lies still continued and have contributed to the insane polarization of the USA.
That is just a few.
