WASHINGTON (AP) - Sen. Marco Rubio has raised roughly $6 million over the last three months for his Republican White House bid.
That's according to an attendee at the Florida senator's donor retreat in Las Vegas, who spoke on the condition of anonymity to share fundraising numbers before they're officially released by the campaign.
Rubio's poll numbers may be rising, but the fundraising total is far less than some of his rivals for the quarter that ended Sept. 30. It reflects what supporters describe as a difficult fundraising environment over the summer.
By comparison, retired neurosurgeon Ben Carson raised more than $20 million over the same period.
The numbers don't reflect money raised by outside groups, including super PACs, that can raise and spend unlimited sums of money to benefit the candidates.
