Walker May Have Mistakenly Tweeted His Candidacy It's not supposed to happen until Monday By John Johnson, Newser Staff Posted Jul 10, 2015 5:37 PM CDT 116 comments Comments Wisconsin Gov. Scott Walker. (AP Photo/Jacquelyn Martin) (Newser) – Psst, Scott Walker is running for president. He doesn't officially announce until Monday, but Politico reports that an apparently mistaken tweet—it's here, for now—seems to have jumped the gun by three days. It shows an image of Walker on stage with the hard-to-misinterpret words, "Scott Walker Is Running For President." The tweet is no longer in the campaign's official feed, which is instead teasing supporters with lines like, "Scott Walker is making a big announcement on Monday and you're invited!" Bloomberg spotted it, too, and campaign officials haven't explained what happened.
