No, it was right the first time. Democrats in the House keep slowly plodding through the motions, each time pretending that this time, THIS time, their chamber will be shown the respect it deserves. If they understood that Trump is going to block everything, they'd have had a subpoena in hand for what's his name's deposition. You're not allowed to testify now? Okay, here's some paperwork, we order you to testify... now.
The Trump administration has obstructed and intimidated every single witness so far. There is every indication they will continue to do so, even with subpoenas, even with impeachment. They need to understand that and plan for it, not simply act outraged every time Lucy pulls the football away and back up for another run at it.
