The Clinton campaign invited U.S. Senator Elizabeth Warren to speak on the first night of the Democratic National Convention, according to the New York Times. This speaking slot is typically earlier than speeches by vice-presidential picks.
Democratic sources who were aware of Warren's invitation said that Clinton has not finalized a running mate, however, and that this does not exclude Warren from being selected as the vice presidential nominee.
Those who received speaking invitations, including Warren, were briefed that their assigned times were subject to change.
Clinton is continuing to meet with the remaining vice-presidential candidates including Senator Cory Booker, New Jersey; Representative Xavier Becerra, Calfornia; Julian Castro and Tom Perez, current cabinet members; and James G. Stavridis, a retired four-star Navy admiral.
Clinton will also be campaigning Thursday in Virginia, with Senator Tim Kaine of Virginia, another possible vice-presidential candidate.
Warren drew attention after speaking at a crowded Cincinnati rally, where she called Donald Trump "a small, insecure money grubber."
