The NRA’s annual meeting will take place May 3-6 in Dallas. Vice President Pence is scheduled to speak there on Friday.
Trump has delivered remarks at each of the past two annual meetings for the gun rights group.
CNN first reported on Trump's planned appearance at the annual meeting.
This speech would come nearly two months after the Trump administration unveiled a series of proposals on school safety and gun restrictions in response to a Feb. 14 shooting at a Parkland, Fla., high school.
