Hawaii Democratic Rep. Ed Case and Arizona Democratic Rep. Greg Stanton became the 12th and 13th House Democrats to call on President Joe Biden to step aside.

“I do not believe President Biden should continue his candidacy for re-election as President,” Rep. Chase said in a statement. “This has nothing to do with his character and record. If it did, there would be no decision to make. This is solely about the future, about the President’s ability to continue in the most difficult job in the world for another four-year term.”

In a statement, Rep. Stanton said Biden was “a fierce defender of American democracy,” but called Trump an “existential threat to our Constitution and the rule of law.”

“The Democratic Party must have a nominee who can effectively make the case against Trump, and have the confidence of the American people to handle the rigors of the hardest job on the planet for the next four years,” Stanton said. “For the sake of American democracy, and to continue to make progress on our shared priorities, I believe it is time for the President to step aside as our nominee.”
