Actually, there are a lot of Senate Republicans who dont want to vote for any more stimulus, including the clean $1200 checks. This has been widely reported. Mitch is covering for them by claiming theyre just against Pelosis pork. The truth is they dont want to vote for any bill, which is why you havent heard Mitch publicly pressuring Pelosi. Theyre fine with the House not sending them anything.
Whether that’s the case or not, it’s kind of irrelevant - the whole mess is hung up in the House and there’s nothing the Senate can do about it. Whether or not Mitch is covering for less than kindly disposed senators has no bearing on it at the current time; it will continue to have no bearing until and unless the House produces a bill.
