WASHINGTON (Reuters) - The National Rifle Association pushed back on Sunday against modest proposals by President Donald Trump and other Republicans to change U.S. gun laws after a school shooting in Florida that killed 17 students and staff.

The powerful gun lobby group does not support Trump's proposals to raise the age limit for buying certain types of guns and to ban bump stocks that enable semi-automatic rifles to shoot hundreds of rounds a minute, a spokeswoman said on ABC's "This Week."
