I saw it mentioned elsewhere that the pubs had threatened to shut down all business by calling a billion useless witnesses unless a deal was made but I don't know the source
Yes, that is what is being reported, but I think that just continues to play into the Democrats hands. At some point they have to start calling Republican's bluffs. Let them slow everything down, then continue to show why we don't have COVID relief or stimulus checks because Republicans are holding it up.
Backing down to everything continues to let Republicans just bully them around. It's very similar to Mitch holding up even letting the Democrats pass the Senate rules to take over the committee chairs. They refused to give and eventually Republicans had to back down. Giving in constantly just makes Republicans more emboldened to continue those tactics.
