President Trump's decision to be the first president in three decades to speak at the annual National Rifle Association convention is drawing heat from two anti-gun groups that now plan to travel to Atlanta to disrupt the massive event.

Moms Demand Action for Gun Sense in America and Everytown for Gun Safety — funded by former New York Mayor Michael Bloomberg — on Monday decried Trump's plans and warned:

"Our volunteers will be in Atlanta during the NRA's annual meeting, just as we have been showing up at town halls and in statehouses across the country to stand up for the safety of our families and communities. We will not be silenced."

The 146th Annual NRA convention will be held April 27-30. It is a combined trade show and public affairs convention where supporters of the Second Amendment typically speak. Last year, for example, several GOP presidential candidates including Trump spoke.

During the campaign, Trump won the NRA's endorsement. The NRA also spent heavily to fight Democrat Hillary Rodham Clinton and anti-gun Democrats.

As a result of Trump's election, Moms, which is part of Everytown, charged in a statement that Trump was paying the NRA back with his speech and pro-gun agenda.

"Make no mistake: The gun lobby is already working to cash in on its investment," said their statement. "Degrading our nation's laws is a dream for NRA lobbyists and a nightmare for public safety," it added.
