The decision to ban guns at an upcoming speech to the National Rifle Association by Vice President Mike Pence in Dallas has prompted discussion on social media, with some painting the move as hypocritical.
Later on Monday, the ban was widened to include "weapons of any kind."
The decision comes on the heels of a gun ban announced by the Secret Service at President Donald Trump's speech last Friday.
Some also pointed out that armed protesters were allowed near speeches by former President Barack Obama.
The Secret Service says guns aren't allowed at such events.
Trump is also expected to appear at the upcoming NRA event.
Others on Twitter argued that the gun ban was purely procedural.
Guns are never allowed inside the secure area of an event in which the president or vice president will appear, said Secret Service Special Agent in Charge Bill Noonan.
"There may have been armed protesters outside the secure areas of events where President Obama appeared, but inside the secure area, that's never been the case," Noonan said.
