(CNN) Sen. Kamala Harris on Wednesday announced that, if she is elected president, she will ban the importation of all AR-15 style assault weapons by executive action if Congress fails to act in the first 100 days of her administration.

Harris made the announcement at a campaign stop in New Hampshire.

"Assault weapons are designed to kill a lot of people in a very short period of time," Harris said.

"I think that this has got to be something that is understood, that we cannot any longer afford to allow people to make this a partisan issue," Harris added. "Those guns, those assault weapons, do not discriminate and determine, 'OK, is the person pointing it at, is it a Democrat or Republican.' "

Harris' proposal is the latest in a series of gun-related executive actions she has promised to take if she wins the Democratic nomination and defeats Donald Trump in 2020. Previously, Harris had said she'd use presidential executive action to mandate near-universal background checks, revoke licenses of gun dealers who break the law, limit fugitives with outstanding arrest warrants from buying guns and close the so-called "boyfriend loophole."
