WASHINGTON (AP) — Ted Cruz's presidential campaign is reporting a $12.2 million fundraising boost over the past three months.

The Republican Texas senator's new fundraising, added to what he raised through the end of June, gives him a total of $26.5 million since he entered the race in late March.

Cruz's fundraising compares favorably with two other Republican candidates who have made their totals public. It's double what Florida Sen. Marco Rubio raised during the same period. Kentucky Sen. Rand Paul brought in $2.5 million between July and the end of last month.

However, retired neurosurgeon Ben Carson's campaign amassed $20 million in that time.

The Associated Press learned of Cruz's figures from a campaign aide, who spoke on condition of anonymity to share fundraising numbers before they're officially released.
