On Thursday, during a committee hearing in the U.S. Senate on gun control legislation, Sen. Ted Cruz (R-TX) and Sen. Dianne Feinstein (D-CA) engaged in a heated exchange over the constitutionality of her support for stricter gun control laws. In posing a question regarding the constitutionality of new gun laws, Cruz lectured Feinstein about the language in the Bill of Rights. Feinstein did not appreciate the lecture and informed Cruz that she was "not a sixth grader." "It seems to me that all of us should begin, as our foundational document, with the Constitution" Cruz began. "And the Second Amendment in the Bill of Rights provides that the right of the people to keep and bear arms shall not be infringed."
