Hillary Clinton enlisted the help of the star of Lyndon Johnson’s infamous “Daisy” ad to offer a condemnation of Republican presidential nominee Donald Trump.

In the Clinton spot, Monique Corzilius Luiz, who was the little girl seen picking daisies in a field in the 1964 ad, expresses concern about the possibility of Trump having access to the nuclear codes given his insistence on being “unpredictable” if elected commander-in-chief.

“The fear of nuclear war that we had as children, I never thought our children would ever have to deal with that again,” she says.

Clips from rallies where Trump has declared his interest in bombing American enemies without regard and being unpredictable are interwoven with clips of an MSNBC spot where host Joe Scarborough discusses the limits on a president who wishes to use nuclear weapons.

The ad comes just days before Election Day amid an increasingly contentious battle for the White House. The Clinton team has repeatedly tried to mark Trump with the same “itchy trigger-finger” image that dogged Republican Presidential nominee Barry Goldwater during the 1964 election.

As TIME History has noted, the Daisy Girl ad, which ran only once, is one of the most infamous and effective campaign ads in history.
