The National Rifle Association (NRA) has obtained an internal Justice Department memo that it says shows President Obama’s gun-control measures would not be effective without firearms seizures and national gun registration, the Associated Press reports.

The gun lobby is citing the nine-page memo in ads running in 15 states, including several swing states with Senate elections next year. In the ad, the NRA says the memo proves that the administration “believes that a gun ban will not work without mandatory gun confiscation” and thinks universal background checks “won’t work without requiring national gun registration,” according to the AP.

Obama has not proposed either of those ideas. Instead, he has called for a ban on assault weapons and high-capacity magazines as well as universal background checks for gun purchases – ideas included in Senate legislation introduced last month by Sen. Dianne Feinstein (D-Calif.).
