After her golden retriever went viral for stealing a burrito, Sen. Elizabeth Warren (D-Mass.) joked that the pressures of "running for first dog" had stressed the pup out.

Warren sat down with MSNBC's Rachel Maddow after ending her presidential campaign and laughed when the subject of her dog's food theft was brought up.

"He said the pressure of running for first dog had finally gotten to him," Warren joked. "I think it was stress-eating."

"It wasn't that he had been offered a burrito," Maddow said. "It was that he availed himself of a burrito."

"You know, he's a dog who stands up and says, 'I'm not waiting for someone to offer, I see what I wanted and I go straight after it,'" Warren said.

She insisted that the dog is "mostly a good boy."

"Mostly," Warren added with a wink.

The dog went viral on Thursday after Gabrielle Farrell, a press secretary on Warren's campaign, tweeted with a 6-second video of Bailey grabbing the food.

He even got an endorsement from Chipotle: "Bailey 2024."

The dog crashed Warren's MSNBC interview at one point, sporting a "consumer watch dog" collar in homage to his owner's work establishing the Consumer Financial Protection Bureau.

"He just came over and ate some of my notes," Maddow said, holding up a piece of paper with a noticeably missing chunk. "Do you wanna know what question he ate? He ate the Michael Bloomberg debate question."

Warren confirmed she was trying to end the former New York City mayor's presidential campaign when she launched a series of attacks on him during the Democratic primary debates.

"Take another bite out of him, boy," Warren told Bailey.

Bailey has been a staple on Warren's social media accounts since the senator received the dog last July as a surprise gift from her husband, Bruce Mann. The pooch is named after George Bailey, the community banker in the movie "It's a Wonderful Life."

He frequently joined her in traveling to campaign events, and there was even a text alert system through her presidential campaign to get frequent photos of the golden retriever.
