A spokesperson for Warren's campaign did not immediately respond to The Hill's request for comment.

Kennedy, a rising star in the Democratic Party, will be among Warren's first high-profile endorsers. 

While most lawmakers have so far withheld their endorsements in the nascent 2020 Democratic presidential primary, a handful of politicians have offered candidates their support.

Kennedy's endorsement could give Warren a boost as she seeks to move beyond the controversy surrounding her past claims of Native American ancestry. 

Criticism of those claims was renewed this week after The Washington Post published a copy of Warren's 1986 registration card for the State Bar of Texas in which she identifies herself as "American Indian."
