Incoming Senate President Bill Galvano is not backing down after finding himself in the crosshairs of the National Rifle Association for receiving a sizable political contribution from a group that backs gun restrictions and has ties to former New York Mayor Michael Bloomberg.

Galvano, a Bradenton Republican who is slated to become Senate president after the November elections, pointed Monday to the Feb. 14 mass shooting at Parkland’s Marjory Stoneman Douglas High School that killed 17 people. After the shooting, lawmakers passed a bill (SB 7026) that included raising the minimum age from 18 to 21 to purchase rifles and other long guns, a restriction the NRA has challenged in federal court.
