Trump, who will almost certainly be the Republican presidential nominee, picked up the endorsement of the National Rifle Association, a politically powerful lobbying group which claims more than 4 million members.

Trump’s remarks at the NRA’s national convention in Louisville, Kentucky, were not a surprise, but they could solidify his status among conservatives who see protecting the U.S. Constitution’s Second Amendment as a top priority.

Trump also planned to meet on Monday with U.S. Senator Bob Corker of Tennessee, a source close to the Trump campaign said. The two are expected to consult on foreign policy. The source said Corker remains on Trump’s list of potential vice presidential running mates.

Clinton, who is close to clinching the Democratic Party’s nomination for the Nov. 8 election, has vowed to take on the gun lobby and expand gun control measures to include comprehensive background checks for gun buyers, including at open-air gun shows and online.

Trump, who is trying to unite the Republican Party behind him after a brutal primary battle, accused Clinton, a former secretary of state to President Barack Obama, of wanting to end the 2nd Amendment, which says in part that the people’s right to keep and bear arms “shall not be infringed.”

The NRA Doesn’t Represent Average Gun Owners

“Hillary Clinton wants to abolish the Second Amendment, not change it; she wants to abolish it,” Trump said.

Clinton campaign senior policy adviser Maya Harris said Trump is peddling falsehoods and denounced “Donald Trump’s conspiracy theories.” She said Clinton believes there are “common-sense steps we can take at the federal level to keep guns out of the hands of criminals” while protecting the Second Amendment.

Trump told the NRA he would eliminate gun-free zones imposed in some areas, noting that the 2015 shooting deaths of four U.S. Marines at an armed forces recruiting center in Chattanooga, Tennessee, took place in a gun-free zone.
