WASHINGTON – Texas U.S. Sen. Ted Cruz is expected to report over $4 million raised in the second quarter, a figure that would leave him trailing Democratic challenger Beto O'Rourke in total receipts.

The Washington Examiner, citing a Cruz "insider," also reported Tuesday that Cruz is expected to list $10 million in the bank.

The report could signify an uptick in fundraising for the Republican incumbent, who has been outraised so far by O'Rourke, a three-term El Paso congressman.

Cruz's campaign declined to confirm the Examiner report, which would put the senator at about $13.1 million in overall receipts for the 2018 midterm election cycle.

O'Rourke has not released its fundraising totals for the last quarter, which covers the period from April to the end of June. He had raised more than $13.2 million by the end of March, with $8 million in the bank.
