U.S. President Joe Biden implored Congress in a White House address Thursday night to approve "common-sense measures" to curb the deadly mass shootings that have shocked Americans, calling for new restrictions that he said would help combat gun violence. Republicans condemn mass shootings and gun violence but have regularly blocked gun control legislation, saying that the proposed restrictions that Democrats favor would impinge on the freedom of law-abiding citizens and are at odds with the right of Americans to possess guns that is enshrined in the Second Amendment to the U.S. Constitution.
