Harris made the comments while boarding a flight to a campaign event.
Vice President Kamala Harris is moving full steam ahead in her bid for the White House, with her campaign saying Sunday it has raised more than $200 million in less than a week.
Former President Donald Trump and his running mate, Sen. JD Vance, have several campaign events set up this week as they aim their attacks on Harris.
Harris has secured commitments from enough delegates to become the presumptive nominee if they all honor their commitment when voting, according to ABC News reporting.
Harris told reporters she still hasn’t decided who her running mate will be as she boarded a plane Tuesday for a trip to Atlanta.
“Madam vice president, have you chosen your VP yet? Have you chosen yet?” ABC News' Fritz Farrow asked.
“Not yet,” Harris said with a smile as she stopped midway up the steps of Air Force Two.
