It is not “Congress’ most prolific tweeter.”
Cornyn, in fact, ran circles — tweeted circles? — around his competition. Between January 1 and March 31, Cornyn sent a whopping 2,198 tweets, more than double the second-place Republican finisher (Arizona Rep. Andy Biggs at 1,006 tweets.)
Interestingly, Cornyn was one of six senators in the top 10 GOP tweeters. Only Chuck Schumer, who sent the 10th most tweets on the Democratic side, broke into the top 10 for congressional Democrats.
The Point: Cornyn clearly loves Twitter. But maybe he loves it too much?
