No idea why Miller would tweet this, or even stranger why you would post it here? He is just looking for nonsense to CREATE and then spread, as well as looking for stupid people to help spread it...
The local Fox affiliate initially posted that both men were in their underwear, which was a lie. Pelosi, who had been in bed when the guy broke in was in underwear, the other guy was dressed however he arrived. The station (KUTV) published a later edition with updates and issued a tiny correction at the end saying they had mistakenly characterized both men as in their underwear., But of course the damage was already done. Lies spread to stupid people much faster than facts, which have to be corrected from lies.
The men were struggling/fighting over the hammer in the hallway and one of them managed to open the door and let the cops in. There was no "3rd person"- just another lie that stupid people (evidently) believe and you post here.
The whole point of this conspiracy theory propaganda is to somehow convince people stupid enough to believe it's true that Pelosi somehow "deserved" whatever happened to him. That deflects from any responsibility that certain wingnuts have for basically demonizing Pelosi and make it seem like loyal patriots would be doing their duty by attacking her.
