SALT LAKE CITY (AP) — With the governor of Texas leading the charge, conservative Republicans in several states are moving to block or undercut President Joe Biden’s COVID-19 vaccine mandates for private employers before the regulations are even issued. The growing battle over what some see as overreach by the federal government is firing up a segment of the Republican Party base, even though many large employers have already decided on their own to require their workers to get the shot. States weighing or advancing bills include Arkansas and Ohio, and there are calls for special sessions in Wyoming, Kansas, South Dakota, Indiana and Tennessee.
