on the congress chambers okaying the election result?

I see it said "only one house member and one senator have to challenge the result" to spur an investigation and a house/senate vote.

BUT, something twigged in me that " the house member/senator CAN CHALLENGE THEIR OWN STATE"... not some other state.

if that's correct, I think it would only be wisconsin where it's somewhat possible that will happen. 

NOTE,

it looks like I'm wrong on that. as Rand Paul of Kentucky is open to idea apparently.. and obviously he's not from one of the swing states
