The 36-year-old Two and a Half Men actor when on a passionate Twitter rant today to defend the ride-hailing service against reports that Uber senior vice president Emil Michael was trying to dig up dirt on journalists who have negatively criticized the company in the media. Kutcher first tweeted, “What is so wrong about digging up dirt on shady journalist? @pando @TechCrunch @Uber.” But he didn’t stop there. The new dad later wrote on the social media site, “So as long as journalist are interested and willing to print half truths as facts… Yes we should question the source,” later adding, “To be clear I speak for my self not @Uber.”
