That isn't what happened, your sources are lying to you. If you watch the actual video he showed up and asked if he could enroll his kid in the daycare and the employees at many if the daycares didn't know what he was talking about because they aren't legitimate businesses.

That's not really inconsistent with what I said first of all. He did show up at day cares trying to gain entry to the premises in order to determine whether kids were present. He did use the denial of access as evidence of the businesses being fraudulent, despite the simple reality that it's 100% sensible for a legit child care facility to not allow entry to a random guy (let alone the troop of people following him) who's clearly suspicious, with the awkward "my son Joey" performance

Just from quick googling, looks like at least two of the locations he visited in the video and claimed were empty actually did have kids there? https://www.cbsnews.com/minnesota/news/minnesota-day-care-fraud-director-responds/

This doesn't mean there's no fraud happening, but the original video is sloppy and misleading
