Warren, who is expected to endorse the presumptive Democratic presidential nominee soon, was unsure about the prospects of having two women running on the ticket in November, Reuters reported.

Warren's advisers have reportedly been in contact with the Clinton campaign in recent weeks, but the Massachusetts senator has not yet spoken to Clinton or the campaign about filling the role of vice president.

Warren is also looking to advance her policy priorities, such as reducing income inequality, which she said are "more progressive" than Clinton's. She is not sure a job as vice president would be the best platform on which to advance those issues.

Still, Warren has signaled interest in the possibility of being Clinton's running mate.

In the past, Warren has been a vocal critic of Trump, slamming him on Twitter and vowing to fight so his "toxic stew of hatred and insecurity never reaches the White House."

Trump also attacked the senator, resurrecting charges that Warren falsely claimed Native American ancestry and dubbing the lawmaker "Pocahontas" on the campaign trail.

Sources close to Warren have said the senator's support of Clinton is driven by her desire to keep Trump out of the White House.

Warren had so far remained neutral during the primary. Her expected endorsement of Clinton could help the Democratic Party unify heading into the general election.
