The presumptive Republican presidential nominee’s recent boast of an $11 million online fundraising surge has been aided by the Prosper Group, an Indianapolis-based digital firm that worked during the GOP primary for Trump rivals Ted Cruz and Marco Rubio, according to four operatives familiar with Trump’s data operation.

To process all that cash, the Trump campaign this month brought on a company called Revv, which did work for the #NeverTrump movement, according to three Republicans.

And last week, the campaign’s top data officials met in San Antonio with officials from the Republican National Committee and a company called Cambridge Analytica to discuss how the firm could help target voters with narrowly framed micro-messages, according to operatives familiar with the meeting. But some of the operatives say there is internal disagreement about whether to hire the firm, which was paid more than $6.7 million by Cruz and his allies.
