and? What hasn't the inquiry being transparent about? Let's look at the steps
1) House calls for an impeachment inquiry
2) House subcommittees call witnesses (some of which have ignored subpoenas or stonewalled during their testimony like Lewondowski and Barr) and the republicans basically have almost as many reps in the subcommittee. Rudy G has already said he will refuse to turn over any requested documents, just like the White House is doing. How is that being transparent?
3) Once the subcommittees have done their investigations they have said they will have an open hearing to the public and all house members
4) Once all that is done, then they will decide if a vote is necessary and if passed will be sent to the senate.
Tell me how that's not being transparent?
That's pretty much how it's always been done.
