Senate Majority Leader Mitch McConnell’s (R-Ky.) reelection campaign has reportedly sold more than 2,000 “Cocaine Mitch” T-shirts, raking in more than $70,000 in campaign contributions.

Roughly four out of five of the purchasers of the $35 T-shirts are first-time donors to the Kentucky Republican’s campaign, according to a report from the Center for Public Integrity.

“One of the things we learned with this whole ‘Cocaine Mitch’ phenomenon is that people are really engaged,” Josh Holmes, a consultant for McConnell’s reelection campaign, told the watchdog organization. “They want content. They want merchandise.”
