Certainly was... don't know by whom or under who's direction yet, but it was undoubtedly tapped...
OH, you want proof.. how bout this, General Flynn's phone call to the Russians that was recorded then leaked came about when Flynn was working in the Trump Tower, meaning the Tower had to be tapped.... no other explanation.... I'm betting the Trump knows a bit more then he's letting on right now.... finding the exact leaker is going to be near impossible I think because of the directive change obummer made in January just before he got out of office... it allows inter-office spreading of information when before it wasn't allowed... especially if they weren't sure if it was true or not...
