From a story on politico.com by Ben White about Texas Senator John Cornyn and gun control:

John Cornyn knew he’d face blowback at his home state’s GOP convention for his bipartisan work on gun safety. He showed up anyway, write Burgess Everett and Olivia Beavers.

Faced with a chorus of boos and a rebuke from the Texas GOP over the weekend, Cornyn got a taste of what the reaction could be on the right for Republicans who vote for the Senate’s bill designed to curb mass shootings in America. What’s more, on Monday evening the NRA announced opposition to the package crafted by a quartet of senators that includes Cornyn, whose A+ rating from the gun group is probably about to take a downgrade.
