GOP Senators Seek Vote On Military Vaccine | GOP Slams President Joe Biden | USA News | News18 A group of Republican senators on Wednesday threatened to withhold their votes to advance the annual National Defense Authorization Act (NDAA) if the chamber doesn’t vote on whether to end the COVID-19 vaccine mandate for members of the military.Led by Sens. Rand Paul (R-Ky.) and Lindsey Graham (R-S.C.), the group said the military is struggling with recruiting and the exodus of thousands for not getting vaccinated hasn’t helped matters.“Congress should take action. And we’re taking action by saying we will not vote to get on the NDAA … unless we have a vote on ending this military vaccine mandate,” Paul told reporters at a press conference at the Capitol.
