The National Rifle Association in the United States have pushed back on Trump’s proposals to gun law reform in the wake of the Marjory Stoneman Douglas High School shooting in which 17 people were killed.

Trump has declared support for raising the age limit to 21 from 18 for buying rifles after the high school shooter was only 19 when he legally purchased a semi-automatic rifle.

Trump has also said he supports legislation to tighten background checks for gun buyers, the details of which he has not yet specified.
