Speaking on the Senate floor Thursday, Sen. Mike Lee (R-Utah) warned that universal background checks could lead to a national registry. He also reminded his colleagues that the government has no business monitoring the legal exercise of any Constitutional right:

“You see, the federal government has no business monitoring when or how often you go to church; what books and newspapers you read; who you vote for; your health conditions; what you eat for breakfast; and the details of your private life– including your lawful exercise of your rights protected by the Second Amendment and other provisions of the Bill of Rights.”
