I don't think the founding fathers every imagined that the house would do something so ridiculous as to vote for impeachment but then refuse or delay sending it to the Senate.
This is just going to look like more partisan games on the part of the Democrats. It's likely to inflame their own base that won't understand the delay. It totally destroys the argument that impeaching Trump was urgent.
The more I think about it, the left may want the FISA court removed.
