Donald Trump said that a Hillary Clinton presidency would lead to a reduction of the Second Amendment.

"We need a Supreme Court that, in my opinion, is going to uphold the Second Amendment — and all amendments — but the Second Amendment, which is under absolute siege," he said at the final debate at the University of Nevada, Las Vegas on Wednesday.

The New York billionaire said it's "imperative" that the United States appoints the "right justices." Trump said he would appoint a Supreme Court justice that would be pro-life, have a conservative bent and would protect the Second Amendment.

Trump then accused Justice Ruth Bader Ginsburg of making "very, very inappropriate statements" about him and the people he represents. In July, Ginsburg called Trump "a faker" and said she "can't imagine" what America would be under his presidency. She later apologized for her comments, saying "judges should avoid commenting on a candidate for public office."

Clinton pushed back and reiterated that she does, in fact, support the Second Amendment. She said she "understands and respect the tradition of gun ownership that goes back to the founding of our country."

The former secretary of state said, however, that she also believes the United States can and should have "reasonable regulation." Clinton said the U.S. should do comprehensive background checks and close loopholes like online and gun show sales.
