Iowa senator Chuck Grassley seems to have control of his own Twitter account, and over the past decade, he has frequently posted about doing "u kno what" at Dairy Queen. Sorry, Chuck, but we don't know what! This week, he posted the phrase again.
The first time "u kno what" showed up on Grassley's Twitter was in 2014. It sent Twitter abuzz.
Senator Grassley explained the cryptic messages in this video.
