The failure to produce this witness, the failure to produce these documents, we consider yet additional strong evidence of obstruction of the constitutional functions of Congress, a coequal branch of government. There are four issues that we are looking at, at least four issues that we are looking at, all that go to the heart of our national security. And by preventing us from hearing from this witness and obtaining these documents, the president and secretary of state are taking actions that prevent us from getting the facts needed to protect the nation’s security.
