FILE - In this Friday, Jan. 20, 2017. file photo, anti-Donald Trump protesters block traffic as they march in the middle of Guadalupe Street next to the University of Texas at Austin on Inauguration Day. In 2017, Republican legislators in at least six states, including Texas, have introduced bills that would shield drivers from civil liability if they unintentionally injure or kill protesters obstructing traffic.
