What's weird about this is that the Pennsylvania state legislature, or at least its leadership, already said Pennsylvania would not make any attempt to appoint its own slate of electors, overriding the popular vote. Then you have a group of legislators trying to get Congress to invalidate Biden's electors.
I guess they want their names attached to a futile gesture, vs. a controversial decision to try to overturn the slate of electors at the state level.
Ooh, looky: Per Newsweek,
Those people listed as signing didn't really sign?
Need to explore.
