The Trump campaign released that 234-page stack of affidavits from poll watchers in Detroit tonight. So far, it's mostly allegations that they couldn't get as close as they wanted to the counting, couldn't re-enter the room after they left, etc. Pretty standard election stuff.
There are a bunch of claims about city workers being hostile to Republicans, cheering when they were escorted out of the room and that kind of thing.
One Republican poll watcher said the independent lawyers observing the process seemed pretty liberal to him.
