The Senate's pause of the OMB proposal is a huge win and shows that taking action makes change, but the fight’s far from over. We need MoCs to take the next step and Revoke the Rule permanently. Contact your MoCs: zurl.co/ygDdC #Vought #Science #SaveScience #StandUpForScience #RevokeTheRule
The OMB Proposal will change American science from a globally collaborative, evidence-based enterprise into one based on political control and isolation. We need MoCs to permanently Revoke the Rule. Contact yours at the link: zurl.co/RWrqE #StandUpForScience #Vought #Science #SaveScience#Trump
