Parkland, Fla., school shooting survivor David Hogg is urging Americans to vote by their morals instead of their party affiliation.

“Don’t just vote for people because they have a 'D' or an 'R' next to their name — make them have an ‘A’ next to their name for ‘American,'” Hogg said late Tuesday on "The Tonight Show With Jimmy Fallon."

“We have to get morally just leaders elected,” he added.

Hogg, who is a survivor of the shooting at Marjory Stoneman Douglas High School, which left 17 dead and 17 injured, is one of the most visible members of the March for Our Lives movement.

Hogg appeared on the late-night show with his sister Lauren, who is 15 and lost four friends in the massacre, to promote their new book "#NeverAgain: A New Generation Draws the Line." 

Hogg wore a badge that said “$1.05.” It represents the amount of money that Sen.

The number has become an unofficial emblem of the student-led gun control movement, with students wearing it at marches and events across the country.

Hogg also criticized lawmakers who have refused to meet with him and fellow gun control activists.

“You go to politicians, you ask for moderate policies, and they won’t even meet with you,” Hogg said.

“Or you do ask for changes and [lawmakers] say ‘yeah’ and nothing happens,” he said.

The proceeds from the Hogg siblings' book, which was released on Tuesday, will go to charity — and taxes.
