Warren is competing for support in Iowa against several Democratic contenders and a recent poll by the Des Moines Register and CNN found her in second place in the Hawkeye State behind Sanders among likely Democratic caucus goers.

That poll was conducted before the most recent Democratic debate in Des Moines, which featured a clash between Warren and Sanders over their conflicting recollections of a 2018 meeting in which Warren claims Sanders told her he didn't believe a woman could win the presidency. Sanders has vehemently denied making such a statement.

Warren's ad released Tuesday seeks to put a focus on the Massachusetts senator taking on Trump and echoes an argument several of her rivals have made that they are best positioned to take on the president in November.
