A top Republican in the Legislature says he does not expect bills targeting fetal tissue research to pass this session. Assembly Speaker Robin Vos says while some Republicans back a bill that would more broadly ban research using human fetal tissue — he doesn’t see them reaching a consensus this spring, before the session ends. Vos says a bill that would close the so-called dark store loophole — which has allowed big box retailers to challenge and lower their tax assessments — probably won’t pass either. Legislation changing the state’s concealed carry laws is another issue he says is unlikely to pass in its current form. Vos says he sees support for a provision that would allow permit holders to have a gun in their vehicle on school grounds, but understands concerns about other provisions that would relax the need to have a permit at all.
