Donald Trump's campaign has paid more than $1.2 million to a small Colorado printing firm connected to a Republican operative who ran a short-lived super PAC in support of Trump — shelling out $624,000 to the company just last month, new filings show.

That made WizBang Solutions, where GOP operative Mike Ciletti works as a director, the campaign's third-highest paid vendor in February. The Commerce City-based company — which was paid for printing and design services — collected more from the Trump campaign last month than it had in all previous months combined.

Trump spokeswoman Hope Hicks did not respond to a request for details about what work WizBang Solutions is doing for the campaign. Ciletti did not return a call seeking comment.

Ciletti's super PAC, Make America Great Again, was shuttered after The Washington Post reported that it had multiple connections to Trump's campaign, despite the real estate developer's insistence that he had not sanctioned a super PAC to back his White House bid.

In fact, Trump appeared at two events for the group and his daughter's mother-in-law gave the super PAC money. In addition, Ciletti, the super PAC's lead consultant, is a longtime business associate of Corey Lewandowski, Trump's campaign manager. The two men worked together when Lewandowski was a top official at the conservative advocacy group Americans for Prosperity. WizBang Solutions was a major vendor to the organization.

While the super PAC was active last year, the Trump campaign paid two firms connected to Ciletti, including WizBang Solutions.

In late October, Ciletti said he was shutting down the super PAC in the wake of The Post's reporting. "It's an issue that I have relationships with Mr. Trump's staff," he said at the time.
