DES MOINES — The Des Moines Register endorsed Senator Elizabeth Warren for the Democratic presidential nomination on Saturday night, calling her “the best leader for these times.”

The newspaper, Iowa’s largest and most influential, gave Ms. Warren a boost just over a week before the caucuses on Feb. 3, when Iowans will take part in the first nominating contest of the primary cycle.

In its editorial, the Register praised Ms. Warren as “a thinker, a policy wonk and a hard worker.”

“Warren’s competence, respect for others and status as the nation’s first female president would be a fitting response to the ignorance, sexism and xenophobia of the Trump Oval Office,” the editorial stated.
