- "I'm ready to say that Elizabeth Warren would make a great vice president," he said
- "We have our nominee. I want to help her be successful," Merkley said
Merkley was the only Senator to endorse Vermont Sen. Bernie Sanders for president.
"Sen. Elizabeth Warren, the president and the vice president all endorse Hillary Clinton. Are you ready to endorse her as well," CNN's Kate Bolduan asked Merkley Friday.
"Certainly, I'm going to support our nominee and our nominee is Secretary Clinton, but what I really want to see is success in November," he said on CNN's "At This Hour with John Berman and Kate Bolduan."
"This is the first time I think that we've heard you say that you're going to support the nominee and acknowledge that the nominee is Hillary Clinton. Is this an endorsement of some sort," Bolduan asked.
"Well, I absolutely support Hillary Clinton. What I've said all along is once a candidate has the majority of the pledged delegates and the majority of the voters and that happened on last Tuesday night, that we have our nominee," he said. "We have our nominee. I want to help her be successful."RELATED: Sen. Jeff Merkley: Sanders will 'absolutely not' make independent bid
