There are procedural tricks for the minority to get a bill on the floor, if it has support of more than half of members (meaning some of the majority would need to sign on to advance it).
They are not often successful, because if the leadership is well organized, they can prevent anyone from their majority from signing on. But I’m not sure that this Speaker knows what he is doing. He seemed to be genuinely surprised when the first impeachment vote failed. But in this case, I doubt Democrats can even get 100% of their own people signing on, because of the funding for Israel. So the hard part might be getting their own people to sign, not the handful of Republicans they will need.
