Apparently they haven't clicked on the link and read the part that shows who else co sponsors the bill & how much support it has....
Doesn't really matter, as it's still grandstanding by all of them. As I recall, in the last Congress the House passed a reciprocity bill but it died in the Senate without being brought to a floor vote by McConnell.
Where were all of these Senators then? Why weren't they pushing McConnell for a floor vote? If they had, it would have passed and Trump would have signed it.
