justice department. they're two very different things. you're right, in terms of what the committee's doing in subpoenaing people and asking for documents, there are some witnesses like roger stone who pled the fifth. there are others like mark meadows who say they will not come in to provide testimony at all. however, the committee is asking a wide swath of people and a wide swath of companies for information. so the committee can actually do its work without some of those people testifying. this is not a criminal investigation on the part of the committee. the committee is trying to put together the most complete picture of what led to the january 6th attack and the january 6th attack on the day itself, as well as the consequences of that attack. that is a picture that they can probably complete without the cooperation of, say, a roger stone. now what the -- what they could also do is take some of that information and refer it to the justice department for possible criminal investigation which has not happened yet. but again, the committee does not necessarily need roger stone
