(CNN) Two weeks after two mass shootings occurred in less than 24 hours, Congress and the White House have not moved closer to passing any kind of gun legislation to address what many are calling a crisis, and some Republican senators, including Sen. Ron Johnson of Wisconsin, don't think any new gun legislation is likely to pass.

Johnson expressed skepticism about any of the legislation options that have been floated in the past two weeks, including so-called red flag laws -- or rules that would allow officials to temporarily remove guns from people in crisis through a court order -- as well as strengthening background checks or mandatory gun buyback programs.

OK, if you propose some kind of gun legislation, first of all, how would that have prevented these tragedies in the past? How would they prevent them in the future?"

Johnson referred to mandatory buyback programs as "compensated confiscation" and said that all of the options that have been proposed are "just a further infringement on second amendment rights."
