Trump Endangering National Security

President Trump's behavior grows increasingly. The Directors of the FBI and CIA and the Director of National Intelligence testified to congress and all laid out the threats the United States faces. They have electronic intercepts, spy satellites and human agents inside all the adversaries. They have experts fluent in the languages and people who have lived in these places or academically studied them for years analyzing the raw data. Then the President throws all this out and says he thinks something else. Based on what, any facts? Then he also denigrates their work and them as people. National security is at stake here. To me, this by itself is impeachable dereliction of duty. The commander in chief is refusing to fulfill his oath to "preserve, protect and defend the constitution of the United States."
