Deny-deny-deny is the CLINTON way-strategy. ( I did not have --- with that woman- I did not inhale-etc.) . One of the most famous Clinton lines, cited over 50 times in one sitting during one investigation, was "I don't recall" and "I do not remember". Having someone "testify" is based on the presumption that they'll be honest under oath. Can we expect anyone closely associated with Hillary to do anything but lie? It's their way of life and it's as easy for them as breathing air.
Hillary Clinton should be forced to testify about her email server. As the United States Secretary of State, she had certain responsibilities, one of them was to abide by the law. Her use of a private email server instead of the State Department email accounts was definitely against the State Department protocol.
Hillary Clinton's email server was not only against the law, but it also put national security at risk. Therefore, Hillary Clinton should have to testify about her email server: Congress has a right to know the details about the server; especially details related to national security. Furthermore, the technology company that maintained her server in Denver, Colorado, should have to testify as well.
No, government officials should not be allowed to force Hillary Clinton to testify about her email server. As a citizen of the United States, Clinton has the constitutional right to testify or to choose not to testify. She also has the right against self-incrimination. Forcing her to testify could lead to the erosion of these important constitutional rights for everyone and would be in violation of the Constitution.
