During an interview with Tucker Carlson, and in an effort to trash President Obama, he said “I just want people to know, the CIA was hacked, and a lot of things taken — that was during the Obama years, That was not during us. That was during the Obama situation. Mike Pompeo is there now doing a fantastic job.” https://www.rawstory.com/2017/03/trump-leaked-classified-cia-intel-to-tucker-carlson-on-live-tv-ranking-house-intel-member/ The information that the CIA was hacked, if true, would be classified information. Now, you might say that the President can declassify information. But normally a President would do it in thoughtful manner, and only after consulting with those that might be affected. Doing it this way, just to attack his predecessor, is very relevant to anybody who might be accumulating evidence about Trump's abuse of power.
