Wrong, Trump tweeted that Obama tapped him, Obama denied that. It was also said at the time the POTUS would never wiretap someone but the FBI or NSA legally could under the juridiction of the FISA court. So Obama did not order a tap of Trump but the campaign may very well have been unsurveilance because there were so many indicators that they were working with the Russians to attack the Dems and undermine the integrity of the election. That warrants a wiretap. And they may have in fact been working with the Russians.
