(CNN) – Days before the release of her new book, Sen. Elizabeth Warren reiterated that she's not angling for a White House bid.

"I'm not running for president," the Massachusetts Democrat said in an interview that aired Sunday on CBS's "Sunday Morning."

Pressed again, she stood firm: "I'm not running for president. You can ask it lots of different ways."

The timing of her book's release on Tuesday has drawn parallels to President Barack Obama, who also published a title two years into his first Senate term back in 2006. He announced his presidential campaign less than a year later.

Warren, who was elected to the Senate in 2012, has become the face of the progressive movement. While former Secretary of State Hillary Clinton is the overwhelming favorite in public opinion polls for the 2016 Democratic nomination, Warren frequently comes in at a distant second or third place.
