No matter what law gets passed anything 2nd Amendment has to pass through the Supreme Court. It's too sensitive for any law to just be accepted and implemented without some kind of Supreme court action. There must of been something else in that bill for Grassley and Ernst to vote for it. Since we don't really know what is in the bill none of us know why they voted that way. There has to be something in it that got their "yes" vote.

Ernst was on TV pushing for US military action in Ukraine. Now we know shes on the take.
