Not going to matter anyway. THe Senate is not going to be back in session until Trump leaves office, so they can't remove Trump with the hearing. Meaning they just wasted so much time for nothing.
They may be able to impeach, but they won't be able to remove him from office, as he will be out before then, so basically he won't be impeached anymore, and the Dems are just wasting their time.
Not going to be able to happen, because I'm sure you need a certain number in the House o pass it, and in case it does pass in the House, you need at least 60 votres in the Senate, and the Dems don't have that.
That depends if they get the WH invitation, which they may not get because of the CV19 scare.
