Let me give you an example. Trump’s aide, Cassidy Hutchinson, testified about Trump grabbing control of the Secret Service agent’s steering wheel. She was quickly thrown on TV in an “emergency hearing”. Considering this account was told to her or overhead, a reasonable investigator would follow up with whomever told this story to Hutchinson and certainly the agents involved. Allegedly, the agents denied this account… but I don’t believe we ever heard their testimony publicly. Nor whoever told this story to Hutchinson in the first place.
It seems to me you didn’t really do much research on this. The entire point of releasing her testimony was to get Secret Service agents such as Bobby Engel and Tony Ornato to come forward and give their version of events. It is just now (Nov 17) that they got Engel back in to address her claims. As for Ornato, it seems like he’ll run out the clock. He retired after her testimony and it turns out text messages from that day from the Secret Service were all deleted. The committee has also brought in other Secret Service agents since her testimony as well. Her statements are something for them to corroborate or refute. The results are presumably forthcoming.
When nobody in the Secret Service will speak up and all their text messages are deleted… well, you release something like Hutchinson’s 2nd-hand testimony to stir that pot and get some of them to come forward with 1st-hand accounts.
Your example does the opposite of proving your point.
Let me put it this way, would you expect an unbiased investigation performed by a group of people who already previously voted impeach Trump for and for the very same incident? Any reasonable person would consider this biased.
Would you say that, following a jury trial with a conviction, everybody in that jury is biased against the defendant? If so, why do they use the same jury to determine sentencing? According to your above analysis, they are now biased and would give an unfairly harsh sentence! And no, any reasonable person would NOT consider that biased.
Convicting somebody of a crime does not mean you are biased against them.
Ideally, an independent commission would be investigating this right now. Unfortunately, that was impossible due to Republican objections. So no matter how fair the committee is, it opens a door for people to say it’s biased. That was beyond obvious from day 1, so it’s amusing to see average people banging the drum of ”they’re biased!” in spite of that.
One could say there’s an inherent bias from ANY member of Congress since they were all present and their lives in danger on Jan 6. But since Republicans wouldn’t allow an independent commission, this is the best and least biased alternative. So far, their actions are not indicative of any partisan bias, with most witnesses called being Republicans, and most of them are (or were) Trump supporters.
My guess is most people didn’t watch the proceedings, and those who are assuming bias aren’t actually examining the results for themselves.
